On SCMI transports whose channels are based on a shared resource the TX
channel area has to be acquired by the agent before placing the desired
command into the channel and it will be then relinquished by the platform
once the related reply has been made available into the channel.
On an RX channel the logic is reversed with the platform acquiring the
channel area and the agent reliquishing it once done by calling the
scmi_clear_channel() helper.
As a consequence, even in case of error, the agent must never try to clear
a TX channel from its side: restrict the existing clear channel call on the
the reply path only to delayed responses since they are indeed coming from
the RX channel.

The card destructor of nm256 driver does merely stopping the running
streams, and it's superfluous for the probe error handling. Moreover,
calling this via the previous devres change would lead to another
problem due to the reverse call order.
This patch moves the setup of the private_free callback after the card
registration, so that it can be used only after fully set up.

In the implicit feedback mode, some parameters are tied between both
playback and capture streams. One of the tied parameters is the
period size, and this can be a problem if the device has different
number of channels to both streams. Assume that an application opens
a playback stream that has an implicit feedback from a capture stream,
and it allocates up to the max period and buffer size as much as
possible. When the capture device supports only more channels than
the playback, the minimum period and buffer sizes become larger than
the sizes the playback stream took. That is, the minimum size will be
over the max size the driver limits, and PCM core sees as if no
available configuration is found, returning -EINVAL mercilessly.
For avoiding this problem, we have to look through the counter part of
audioformat list for each sync ep, and checks the channels. If more
channels are found there, we reduce the max period and buffer sizes
accordingly.
You may wonder that the patch adds only the evaluation of channels
between streams, and what about other parameters? Both the format and
the rate are tied in the implicit fb mode, hence they are always
identical.
The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature. Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().
This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.

The previous cleanup with devres forgot to replace the snd_card_free()
call with the devm version. Moreover, it still needs the manual call
of snd_card_free() at the probe error path, otherwise the reverse
order of the releases may happen. This patch addresses those issues.
Fixes: 499ddc16394c ("ALSA: sis7019: Allocate resources with device-managed APIs") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20220412102636.16000-28-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Kamal Mostafa <kamal@canonical.com> Signed-off-by: Stefan Bader <stefan.bader@canonical.com>
This is a small helper function to handle the error path more easily
when an error happens during the probe for the device with the
device-managed card. Since devres releases in the reverser order of
the creations, usually snd_card_free() gets called at the last in the
probe error path unless it already reached snd_card_register() calls.
Due to this nature, when a driver expects the resource releases in
card->private_free, this might be called too lately.
As a workaround, one should call the probe like:
static int __some_probe(...) { // do real probe.... }
static int some_probe(...)
{
return snd_card_free_on_error(dev, __some_probe(dev, ...));
}
so that the snd_card_free() is called explicitly at the beginning of
the error path from the probe.
This function will be used in the upcoming fixes to address the
regressions by devres usages.
Running generic/406 causes the following WARNING in btrfs_destroy_inode()
which tells there are outstanding extents left.
In btrfs_get_blocks_direct_write(), we reserve a temporary outstanding
extents with btrfs_delalloc_reserve_metadata() (or indirectly from
btrfs_delalloc_reserve_space(()). We then release the outstanding extents
with btrfs_delalloc_release_extents(). However, the "len" can be modified
in the COW case, which releases fewer outstanding extents than expected.
Fix it by calling btrfs_delalloc_release_extents() for the original length.
To reproduce the warning, the filesystem should be 1 GiB. It's
triggering a short-write, due to not being able to allocate a large
extent and instead allocating a smaller one.
In some cases, the IPA hardware needs to request the always-on
subsystem (AOSS) to coordinate with the IPA microcontroller to
retain IPA register values at power collapse. This is done by
issuing a QMP request to the AOSS microcontroller. A similar
request ondoes that request.
We must get and hold the "QMP" handle early, because we might get
back EPROBE_DEFER for that. But the actual request should be sent
while we know the IPA clock is active, and when we know the
microcontroller is operational.

ACPI: processor idle: Allow playing dead in C3 state
The above patch is trying to enter C3 state during init, what is causing
a T40 system freeze. I have not found a similar issue on any other of my
32-bit machines.
The fix is to add another exception to the processor_power_dmi_table[] list.
As a result the dmesg shows as expected:
[2.155398] ACPI: IBM ThinkPad T40 detected - limiting to C2 max_cstate. Override with "processor.max_cstate=9"
[2.155404] ACPI: processor limited to max C-state 2

When `osc_pc_lpi_support_confirmed` is set through `_OSC` and `_LPI` is
populated then the cpuidle driver assumes that LPI is fully functional.
However currently the kernel only provides architectural support for LPI
on ARM. This leads to high power consumption on X86 platforms that
otherwise try to enable LPI.
So probe whether or not LPI support is implemented before enabling LPI in
the kernel. This is done by overloading `acpi_processor_ffh_lpi_probe` to
check whether it returns `-EOPNOTSUPP`. It also means that all future
implementations of `acpi_processor_ffh_lpi_probe` will need to follow
these semantics as well.

The former patch "defer 6pack kfree after unregister_netdev" reorders
the kfree of two buffer after the unregister_netdev to prevent the race
condition. It also adds free_netdev() function in sixpack_close(), which
is a direct copy from the similar code in mkiss_close().
However, in sixpack driver, the flag needs_free_netdev is set to true in
sp_setup(), hence the unregister_netdev() will free the netdev
automatically. Therefore, as the sp is netdev_priv, use-after-free
occurs.
This patch removes the needs_free_netdev = true and just let the
free_netdev to finish this deallocation task.

[How]
Update the value in the constructor to 0x6 so we're checking the right

It worked before by accident, but can falsely assert 0 depending on HW

During controller reset, the driver tries to flush all the pending firmware

To limit this deadlock, continue with the controller reset handling without

Don't issue the soft reset if internal commands are flushed out with reset
status. Soft reset needs to be issued only if commands are really timed
out.

scsi: mpi3mr: Use scnprintf() instead of snprintf()
BugLink: https://bugs.launchpad.net/bugs/1967116
I intended to move from snprintf() to scnprintf() in the previous patch but
I messed up and did not do that. The result of my bug is that it this
function could trigger a WARN() if the buffer is too large.

If we change from scnprintf() to snprintf() that lets us remove the if
bytes_wrote < sizeof(protocol) checks. Also, we can use bytes_wrote ? ","
: "" to print the comma and remove the separate if statement and the
"is_string_nonempty" variable.
