ASoC: rt5645: add fallback case for jack detection support
Commit 78f5605c0329 ("ASoC: rt5645: cleanup DMI matching code") did a
lot of useful cleanups. This patch adds a default case to enable
jack detection if there is no pdata, device property or quirk.
The chosen jd-mode3 is the most common and should limit the addition
of new DMI-based quirks. Existing DMI quirks which only set this mode
are left as is and not removed.

The actual number of mics can currently not be configured in the device

a single mic is treated as a stereo/multi channel device, even though
only one channel carries audio data.

in the device tree. When specified this value overwrites the default

ASoC: rockchip: i2s: fix playback after runtime resume
When restoring registers during runtime resume, we must not write to
I2S_TXDR which is the transmit FIFO as this queues up a sample to be
output and pushes all of the output channels down by one.
This can be demonstrated with the speaker-test utility:
for i in a b c; do speaker-test -c 2 -s 1; done
which should play a test through the left speaker three times but if the
I2S hardware starts runtime suspended the first sample will be played
through the right speaker.
Fix this by marking I2S_TXDR as volatile (which also requires marking it
as readble, even though it technically isn't). This seems to be the
most robust fix, the alternative of giving I2S_TXDR a default value is
more fragile since it does not prevent regcache writing to the register
in all circumstances.
While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these
are not writable so they do not suffer from the same problem as I2S_TXDR
but reading from I2S_RXDR does suffer from a similar problem.

replaced del_timer_sync(&led_cdev->blink_timer) with led_stop_software_blink()

zeroes blink_delay_on and blink_delay_off properties of the struct led_classdev.
Cleansing of the latter ones wasn't required to fix the original issue but
wasn't considered harmful. It nonetheless turned out to be so in case when
pointer to one or both props is passed to led_blink_set() like in the
ledtrig-timer.c. In such cases zeroes are passed later in delay_on and/or
delay_off arguments to led_blink_setup(), which results either in stopping
the software blinking or setting blinking frequency always to 1Hz.
Avoid using led_stop_software_blink() and add a single call required
to clear LED_BLINK_SW flag, which was the only needed modification to
fix the original issue.

mtd: nand: pxa3xx: Fix READOOB implementation
In the current driver, OOB bytes are accessed in raw mode, and when a
page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the
driver must read the whole spare area (64 bytes in case of a 2k page,
16 bytes for a 512 page). The driver was only reading the free OOB
bytes, which was leaving some unread data in the FIFO and was somehow
leading to a timeout.
We could patch the driver to read ->spare_size + ->ecc_size instead of
just ->spare_size when READOOB is requested, but we'd better make
in-band and OOB accesses consistent.
Since the driver is always accessing in-band data in non-raw mode (with
the ECC engine enabled), we should also access OOB data in this mode.
That's particularly useful when using the BCH engine because in this
mode the free OOB bytes are also ECC protected.

apparmor: fix regression in mount mediation when feature set is pinned
When the mount code was refactored for Labels it was not correctly
updated to check whether policy supported mediation of the mount
class. This causes a regression when the kernel feature set is
reported as supporting mount and policy is pinned to a feature set
that does not support mount mediation.

Pull more x86 pti fixes from Thomas Gleixner:
"Another small stash of fixes for fallout from the PTI work:
- Fix the modules vs. KASAN breakage which was caused by making
MODULES_END depend of the fixmap size. That was done when the cpu
entry area moved into the fixmap, but now that we have a separate
map space for that this is causing more issues than it solves.
- Use the proper cache flush methods for the debugstore buffers as
they are mapped/unmapped during runtime and not statically mapped
at boot time like the rest of the cpu entry area.
- Make the map layout of the cpu_entry_area consistent for 4 and 5
level paging and fix the KASLR vaddr_end wreckage.
- Use PER_CPU_EXPORT for per cpu variable and while at it unbreak
nvidia gfx drivers by dropping the GPL export. The subject line of
the commit tells it the other way around, but I noticed that too
late.
- Fix the ASM alternative macros so they can be used in the middle of
an inline asm block.
- Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack
vector is properly identified. The Spectre mitigations will come
with their own bug bits later"
