Subject: [GIT PULL] sound fixes for 4.15-rc1

Linus,

please pull sound fixes for v4.15-rc1 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-fix-4.15-rc1

The topmost commit is 9ceace3c9c18c67676e75141032a65a8e01f9a7a

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

sound fixes for 4.15-rc1

All commits found here are small fixes for regression or stable:
- PCM timestamp behavior fix that could be seen as a regression
- Remove spurious WARN_ON() from ALSA timer 32bit compat ioctl
- HD-audio HDMI/DP channel mapping fix for 32bit archs
- Fix the previous fix for HD-audio initialization code
- More hardening USB-audio against malicious USB descriptors
- HD-audio quirks/fixes (Realtek codec, AMD controller)
- Missing help text for the recent Intel SST kconfig change

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

Henrik Eriksson (1):
      ALSA: pcm: update tstamp only if audio_tstamp changed

Julian Scheel (1):
      ALSA: usb-audio: uac1: Invalidate ctl on interrupt

      ALSA: hda/realtek: Add headset mic support for Intel NUC Skull Canyon

Kailang Yang (2):
      ALSA: hda/realtek - Fix ALC275 no sound issue
      ALSA: hda/realtek - Fix ALC700 family no sound issue

Takashi Iwai (7):
      ALSA: hda: Fix too short HDMI/DP chmap reporting
      ALSA: timer: Remove kernel warning at compat ioctl error paths
      ALSA: usb-audio: Add sanity checks to FE parser
      ALSA: usb-audio: Fix potential out-of-bound access at parsing SU
      ALSA: usb-audio: Fix potential zero-division at parsing FU
      ALSA: usb-audio: Add sanity checks in v2 clock parsers
      ALSA: hda - Fix yet remaining issue with vmaster 0dB initialization

Vijendar Mukunda (1):
      ALSA: hda: Add Raven PCI ID

Vinod Koul (1):
