Linus,

please pull sound fixes for v4.14-rc8 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-4.14-rc8

The topmost commit is a53a0ab8ff725672fcb47bb9a5ef75fce45679d0

----------------------------------------------------------------

sound fixes for 4.14

Unfortunately we still have received a significant amount of changes
at the late stage, but at least all are small and clear fixes.

There are two fixes for ALSA core stuff, yet another timer race fix
and sequencer lockdep annotation fix. Both are spotted by syzkaller,
and not too serious but better to paper over quickly.

All other commits are about ASoC drivers, most notably, a revert of
RT5514 hotword control that was included in 4.14-rc (due to a kind of
abuse of kctl TLV ABI), together with topology API fixes and other
device-specific small fixes that should go for stable, too.
