The core received rewrites in PCM buffer allocation handling and locking optimizations, PCM rate updates followed by lots of cleanups. In ASoC side, the legacy Intel drivers have been deprecated by AVS drivers which leaded to the significant amount of code reduction. SoundWire driver updates and other cleanups contributed more code reduction, too. USB-audio driver received a large cleanup of its big quirk table, and the old snd_print*() API usages in many legacy drivers are replaced with the standard print API.

Pull sound updates from Takashi Iwai:
 "A fairly big update at this time, both in core and driver sides.

  The core received rewrites in PCM buffer allocation handling and
  locking optimizations, PCM rate updates followed by lots of cleanups.

  In ASoC side, the legacy Intel drivers have been deprecated by AVS
  drivers which leaded to the significant amount of code reduction.
  SoundWire driver updates and other cleanups contributed more code
  reduction, too.

  USB-audio driver received a large cleanup of its big quirk table, and
  the old snd_print*() API usages in many legacy drivers are replaced
  with the standard print API.

  Here are some highlights:

  Core:
   - More optimized locking in ALSA control code
   - Rewrites of memalloc helpers for better DMA API usage
   - Drop of obsoleted vmalloc PCM buffer helper API
   - Continued MIDI2 UMP updates
   - Support of a new user-space driven timer instance
   - Update for more PCM support rates and cleanups
   - Xrun counter report in the proc files

  ASoC:
   - Continued simplification and cleanup works for ASoC
   - Extensive cleanups and refactoring of the Soundwire drivers
   - Removal of Intel machine support obsoleted by the AVS driver
   - Lots of DT schema conversions
   - Machine support for many AMD and Intel x86 platforms
   - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek
     RTL1320 SoundWire and rev C, and Texas Instruments TAS2563

  USB-audio:
   - Add support of multiple control interfaces
   - A large rewrite of quirk table with macros
   - Support for RME Digiface USB

  HD-audio:
   - Cleanup of quirk code for Samsung Galaxy laptops
   - Clean up of detection of Cirrus codecs
   - C-Media CM9825 HD-audio codec support

  Others:
   - Rewrites to standard print API in a lot of legacy drivers"
