Merge tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "No dramatic changes are found in this development cycle, but as usual,
  many commits are applied in a wide range of drivers.

  Most of big changes are in ASoC, where a few bits of framework work
  and quite a lot of cleanups and improvements to existing code have
  been done. The rest are usual stuff, a few HD-audio and USB-audio
  quirks and fixes, as well as the drop of kthread usages in the whole
  subsystem.

  Below are some highlights:

  ASoC:
   - support for stereo DAPM controls
   - some initial work on the of-graph sound card
   - regmap conversions of the remaining AC'97 drivers
   - a new version of the topology ABI; this should be backward
     compatible
   - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
     Intel skylake, atom-sst
   - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
     Realtek RT5665

  USB-audio:
   - yet another race fix at disconnection
   - tolerated packet size calculation for some Android devices
   - quirks for Axe-Fx II, QuickCam, TEAC 501/503

  HD-audio:
   - improvement of Dell pin fixup mapping
   - quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

  Misc:
   - replace all kthread usages with simple works"
