ASoC: Updates for v5.7

This is a very big update for the core since Morimoto-san has been
rather busy continuing his refactorings to clean up a lot of the cruft
that we have accumilated over the years. We've also gained several new
drivers, including initial (but still not complete) parts of the Intel
SoundWire support.

- Lots of refactorings to modernize the code from Morimoto-san.
- Conversion of SND_SOC_ALL_CODECS to use imply from Geert Uytterhoeven.
- Continued refactoring and fixing of the Intel support.
- Soundwire and more advanced clocking support for Realtek RT5682.
- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and
TLV320ADCX140.

Merge tag 'for-5.6/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

- Fix request-based DM's congestion_fn and actually wire it up to the
bdi.

- Extend dm-bio-record to track additional struct bio members needed by
DM integrity target.

- Fix DM core to properly advertise that a device is suspended during
unload (between the presuspend and postsuspend hooks). This change is
a prereq for related DM integrity and DM writecache fixes. It
elevates DM integrity's 'suspending' state tracking to DM core.

- Four stable fixes for DM integrity target.

- Fix crash in DM cache target due to incorrect work item cancelling.

- Fix DM thin metadata lockdep warning that was introduced during 5.6
merge window.

- Fix DM zoned target's chunk work refcounting that regressed during
recent conversion to refcount_t.

- Bump the minor version for DM core and all target versions that have
seen interface changes or important fixes during the 5.6 cycle.

dm zoned: Fix reference counter initial value of chunk works

Dm-zoned initializes reference counters of new chunk works with zero
value and refcount_inc() is called to increment the counter. However, the
refcount_inc() function handles the addition to zero value as an error
and triggers the warning as follows:

refcount_t: addition on 0; use-after-free.

After this warning, following refcount API calls for the counter all fail
to change the counter value.

Fix this by setting the initial reference counter value not zero but one
for the new chunk works. Instead, do not call refcount_inc() via
dmz_get_chunk_work() for the new chunks works.

The failure was observed with linux version 5.4 with CONFIG_REFCOUNT_FULL
enabled. Refcount rework was merged to linux version 5.5 by the
commit 168829ad09ca ("Merge branch 'locking-core-for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip"). After this
commit, CONFIG_REFCOUNT_FULL was removed and the failure was observed
regardless of kernel configuration.

Linux version 4.20 merged the commit 092b5648760a ("dm zoned: target: use
refcount_t for dm zoned reference counters"). Before this commit, dm
zoned used atomic_t APIs which does not check addition to zero, then this
fix is not necessary.
