Merge tag 'sound-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There have been little changes in ALSA core stuff, but ASoC core still
  kept rolling for the continued restructuring. The rest are lots of
  small driver-specific changes and some minor API updates. Here are
  highlights:

  General:
  - Appropriate fall-through annotations everywhere
  - Some code cleanup in memalloc code, handling non-cacahed pages more
    commonly in the helper
  - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently

  Drivers:
  - More HD-audio CA0132 codec improvement for supporting other Creative
    boards
  - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
    give move support of existing HD-audio devices with DSP
  - A few device-specific HD-audio quirks as usual
  - New quirk for RME CC devices and correction for B&W PX for USB-audio
  - FireWire: code refactoring including devres usages

  ASoC Core:
  - Continued componentization works; it's almost done!
  - A bunch of new for_each_foo macros
  - Cleanups and fixes in DAPM code

  ASoC Drivers:
  - MCLK support for several different devices, including CS42L51, STM32
    SAI, and MAX98373
  - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
    MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
    TI PCM3060"
