A previous commit removed the panel-dpi driver, which made the
SOM-LV video stop working because it relied on the DPI driver
for setting video timings. Now that the simple-panel driver is
available in omap2plus, this patch migrates the SOM-LV dev kits
to use a similar panel and remove the manual timing requirements.
A similar patch was already done and applied to the Torpedo family.

ovl_path_open() is used by readdir and copy-up routines.
ovl_permission() theoretically already checked copy up permissions, but it
doesn't hurt to re-do these checks during the actual copy-up.
For directory reading ovl_permission() only checks access to topmost
underlying layer. Readdir on a merged directory accesses layers below the
topmost one as well. Permission wasn't checked for these layers.
Note: modifying ovl_permission() to perform this check would be far more
complex and hence more bug prone. The result is less precise permissions
returned in access(2). If this turns out to be an issue, we can revisit
this bug.

tty: hvcs: Don't NULL tty->driver_data until hvcs_cleanup()
BugLink: https://bugs.launchpad.net/bugs/1892546
The code currently NULLs tty->driver_data in hvcs_close() with the
intent of informing the next call to hvcs_open() that device needs to be
reconfigured. However, when hvcs_cleanup() is called we copy hvcsd from
tty->driver_data which was previoulsy NULLed by hvcs_close() and our
call to tty_port_put(&hvcsd->port) doesn't actually do anything since
&hvcsd->port ends up translating to NULL by chance. This has the side
effect that when hvcs_remove() is called we have one too many port
references preventing hvcs_destuct_port() from ever being called. This
also prevents us from reusing the /dev/hvcsX node in a future
hvcs_probe() and we can eventually run out of /dev/hvcsX devices.
Fix this by waiting to NULL tty->driver_data in hvcs_cleanup().
Said commit causes same-sized kmemcaches to become unmergeable, and when a
new kmemcache is created, it will fail creating the sysfs entry, making the
kmemcache creation to fail.
Considering the original commit fix a leak but causes a different leak and
failures to create kmemcaches, the revert is preferable until a proper fix
is developed.

netpoll from accessing rings before init is complete. However, the
same is not done for fresh napi instances in netif_napi_add(),
even though we expect NAPI instances to be added as disabled.
This causes crashes during driver reconfiguration (enabling XDP,
changing the channel count) - if there is any printk() after
netif_napi_add() but before napi_enable().
To ensure memory ordering is correct we need to use RCU accessors.

One problem is that wait_for_completion() from flush_workqueue() from
nbd_start_device_ioctl() from nbd_ioctl() cannot be completed when
nbd_start_device_ioctl() received a signal at wait_event_interruptible(),
for tipc_shutdown() from kernel_sock_shutdown(SHUT_RDWR) from
nbd_mark_nsock_dead() from sock_shutdown() from nbd_start_device_ioctl()
is failing to wake up a WQ thread sleeping at wait_woken() from
tipc_wait_for_rcvmsg() from sock_recvmsg() from sock_xmit() from
nbd_read_stat() from recv_work() scheduled by nbd_start_device() from
nbd_start_device_ioctl(). Fix this problem by always invoking
sk->sk_state_change() (like inet_shutdown() does) when tipc_shutdown() is
called.
The other problem is that tipc_wait_for_rcvmsg() cannot return when
tipc_shutdown() is called, for tipc_shutdown() sets sk->sk_shutdown to
SEND_SHUTDOWN (despite "how" is SHUT_RDWR) while tipc_wait_for_rcvmsg()
needs sk->sk_shutdown set to RCV_SHUTDOWN or SHUTDOWN_MASK. Fix this
problem by setting sk->sk_shutdown to SHUTDOWN_MASK (like inet_shutdown()
does) when the socket is connectionless.
Since commit 9c66d1564676 ("taprio: Add support for hardware
offloading") there's a bit of inconsistency when offloading schedules
to the hardware:
In software mode, the gate masks are specified in terms of traffic
classes, so if say "sched-entry S 03 20000", it means that the traffic
classes 0 and 1 are open for 20us; when taprio is offloaded to
hardware, the gate masks are specified in terms of hardware queues.
The idea here is to fix hardware offloading, so schedules in hardware
and software mode have the same behavior. What's needed to do is to
map traffic classes to queues when applying the offload to the driver.

With disabling bh in the whole sctp_get_port_local(), when

There's no need to disable bh in the whole function of

This patch fixes two main problems seen when removing NetLabel
mappings: memory leaks and potentially extra audit noise.
The memory leaks are caused by not properly free'ing the mapping's
address selector struct when free'ing the entire entry as well as
not properly cleaning up a temporary mapping entry when adding new
address selectors to an existing entry. This patch fixes both these
problems such that kmemleak reports no NetLabel associated leaks
after running the SELinux test suite.
The potentially extra audit noise was caused by the auditing code in
netlbl_domhsh_remove_entry() being called regardless of the entry's
validity. If another thread had already marked the entry as invalid,
but not removed/free'd it from the list of mappings, then it was
possible that an additional mapping removal audit record would be
generated. This patch fixes this by returning early from the removal
function when the entry was previously marked invalid. This change
also had the side benefit of improving the code by decreasing the
indentation level of large chunk of code by one (accounting for most
of the diffstat).

There is a race between the assignment of `table->data` and write value
to the pointer of `table->data` in the __do_proc_doulongvec_minmax() on
the other thread.
Fix this by duplicating the `table`, and only update the duplicate of
it. And introduce a helper of proc_hugetlb_doulongvec_minmax() to
simplify the code.
The usage of "capture group (...)" in the immediate condition after `&&`
results in `$1` being uninitialized. This issues a warning "Use of
uninitialized value $1 in regexp compilation at ./scripts/checkpatch.pl
line 2638".
I noticed this bug while running checkpatch on the set of commits from
v5.7 to v5.8-rc1 of the kernel on the commits with a diff content in
their commit message.
This bug was introduced in the script by commit e518e9a59ec3
("checkpatch: emit an error when there's a diff in a changelog"). It
has been in the script since then.
The author intended to store the match made by capture group in variable
`$1`. This should have contained the name of the file as `[\w/]+`
matched. However, this couldn't be accomplished due to usage of capture
group and `$1` in the same regular expression.
Fix this by placing the capture group in the condition before `&&`.
Thus, `$1` can be initialized to the text that capture group matches
thereby setting it to the desired and required value.

Tegra210 and later has a separate sdmmc_legacy_tm (TMCLK) used by Tegra
SDMMC hawdware for data timeout to achive better timeout than using
SDCLK and using TMCLK is recommended.
USE_TMCLK_FOR_DATA_TIMEOUT bit in Tegra SDMMC register
SDHCI_TEGRA_VENDOR_SYS_SW_CTRL can be used to choose either TMCLK or
SDCLK for data timeout.
Default USE_TMCLK_FOR_DATA_TIMEOUT bit is set to 1 and TMCLK is used
for data timeout by Tegra SDMMC hardware and having TMCLK not enabled
is not recommended.
So, this patch adds quirk NVQUIRK_HAS_TMCLK for SoC having separate

SR-IOV VFs do not implement the memory enable bit of the command
register, therefore this bit is not set in config space after
pci_enable_device(). This leads to an unintended difference
between PF and VF in hand-off state to the user. We can correct
this by setting the initial value of the memory enable bit in our
virtualized config space. There's really no need however to
ever fault a user on a VF though as this would only indicate an
error in the user's management of the enable bit, versus a PF
where the same access could trigger hardware faults.

Commit 935fcc56abc3 ("dm mpath: only flush workqueue when needed")
changed flush_multipath_work() to avoid needless workqueue
flushing (of a multipath global workqueue). But that change didn't
realize the surrounding flush_multipath_work() code should also only
run if 'pg_init_in_progress' is set.
Fix this by only doing all of flush_multipath_work()'s PG init related
work if 'pg_init_in_progress' is set.
Otherwise multipath_wait_for_pg_init_completion() will run
unconditionally but the preceeding flush_workqueue(kmpath_handlerd)
may not. This could lead to deadlock (though only if kmpath_handlerd
never runs a corresponding work to decrement 'pg_init_in_progress').
It could also be, though highly unlikely, that the kmpath_handlerd
work that does PG init completes before 'pg_init_in_progress' is set,
and then an intervening DM table reload's multipath_postsuspend()
triggers flush_multipath_work().

The function dax_direct_access doesn't take partitions into account,
it always maps pages from the beginning of the device. Therefore,

ioc_pd_free() grabs irq-safe ioc->lock without ensuring that irq is disabled
when it can be called with irq disabled or enabled. This has a small chance
of causing A-A deadlocks and triggers lockdep splats. Use irqsave operations
instead.
All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.
Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.
If a driver leaves the limit settings as the defaults, then we don't
initialize bdi->io_pages. This means that file systems may need to
work around bdi->io_pages == 0, which is somewhat messy.
Initialize the default value just like we do for ->ra_pages.

For Intel controllers, SDHCI_RESET_ALL resets also CQHCI registers.
Normally, SDHCI_RESET_ALL is not used while CQHCI is enabled, but that can
happen on the error path. e.g. if mmc_cqe_recovery() fails, mmc_blk_reset()
is called which, for a eMMC that does not support HW Reset, will cycle the
bus power and the driver will perform SDHCI_RESET_ALL.
So whenever performing SDHCI_RESET_ALL ensure CQHCI is deactivated.
That will force the driver to reinitialize CQHCI when it is next used.
A similar change was done already for sdhci-msm, and other drivers using
CQHCI might benefit from a similar change, if they also have CQHCI reset
by SDHCI_RESET_ALL.

There've been quite a few regression reports about the lowered volume
(reduced to ca 65% from the previous level) on Lenovo Thinkpad X1
after the commit d2cd795c4ece ("ALSA: hda - fixup for the bass speaker
on Lenovo Carbon X1 7th gen"). Although the commit itself does the
right thing from HD-audio POV in order to have a volume control for
bass speakers, it seems that the machine has some secret recipe under
the hood.
Through experiments, Benjamin Poirier found out that the following
routing gives the best result:
* DAC1 (NID 0x02) -> Speaker pin (NID 0x14)
* DAC2 (NID 0x03) -> Shared by both Bass Speaker pin (NID 0x17) &
Headphone pin (0x21)
* DAC3 (NID 0x06) -> Unused
DAC1 seems to have some equalizer internally applied, and you'd get
again the output in a bad quality if you connect this to the
headphone pin. Hence the headphone is connected to DAC2, which is now
shared with the bass speaker pin. DAC3 has no volume amp, hence it's
not connected at all.
For achieving the routing above, this patch introduced a couple of
workarounds:
* The connection list of bass speaker pin (NID 0x17) is reduced not to
include DAC3 (NID 0x06)
* Pass preferred_pairs array to specify the fixed connection
Here, both workarounds are needed because the generic parser prefers
the individual DAC assignment over others.
When the routing above is applied, the generic parser creates the two
volume controls "Front" and "Bass Speaker". Since we have only two
DACs for three output pins, those are not fully controlling each
output individually, and it would confuse PulseAudio. For avoiding
the pitfall, in this patch, we rename those volume controls to some
unique ones ("DAC1" and "DAC2"). Then PulseAudio ignore them and
concentrate only on the still good-working "Master" volume control.
If a user still wants to control each DAC volume, they can still
change manually via "DAC1" and "DAC2" volume controls.
The Galaxy Book Ion NT950XCJ-X716A (15 inches) uses the same ALC298
codec as other Samsung laptops which have the no headphone sound bug. I
confirmed on my own hardware that this fixes the bug.
This also correct the model name for the 13 inches version. It was
incorrectly referenced as NT950XCJ-X716A in commit e17f02d05. But it
should have been NP930XCJ-K01US.
Tascam FE-8 is known to support communication by asynchronous transaction
only. The support can be implemented in userspace application and
snd-firewire-ctl-services project has the support. However, ALSA
firewire-tascam driver is bound to the model.
This commit changes device entries so that the model is excluded. In a
commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing
processing"), I addressed to the concern that version field in
configuration differs depending on installed firmware. However, as long
as I checked, the version number is fixed. It's safe to return version
number back to modalias.
Following Christian Lachner's patch for Gigabyte X570-based motherboards,
also patch the MSI X570-A PRO motherboard; the ALC1220 codec requires the
same workaround for Clevo laptops to enforce the DAC/mixer connection
path. Set up a quirk entry for that.
I suspect most if all X570 motherboards will require similar patches.
[ The entries reordered in the SSID order -- tiwai ]
Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to.
However, as long as he investigated, the design of this model is hardly
similar to the one of Digi 00x family. It's better to exclude the model
from modalias of ALSA firewire-digi00x driver.
This commit changes device entries so that the model is excluded.
When system is suspended with active audio playback to HDMI/DP, two
alternative sequences can happen at resume:
a) monitor is detected first and ALSA prepare follows normal
stream setup sequence, or
b) ALSA prepare is called first, but monitor is not yet detected,
so PCM is restarted without a pin,
In case of (b), on i915 systems, haswell_verify_D0() is not called at
resume and the pin power state may be incorrect. Result is lack of audio
after resume with no error reported back to user-space.
Fix the problem by always verifying converter and pin state in the
i915_pin_cvt_fixup().
The PCM OSS mulaw plugin has a check of the format of the counter part
whether it's a linear format. The check is with snd_BUG_ON() that
emits WARN_ON() when the debug config is set, and it confuses
syzkaller as if it were a serious issue. Let's drop snd_BUG_ON() for
avoiding that.
While we're at it, correct the error code to a more suitable, EINVAL.
snd_ca0106_spi_write() returns 1 on error, snd_ca0106_pcm_power_dac()
is returning the error code directly, and the caller is expecting an
negative error code
The problem is we're doing a copy_to_user() while holding tree locks,
which can deadlock if we have to do a page fault for the copy_to_user().
This exists even without my locking changes, so it needs to be fixed.
Rework the search ioctl to do the pre-fault and then
copy_to_user_nofault for the copying.
