Merge tag 'sound-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "The majority of this update is about ASoC, including a few new
  drivers, and the rest are mostly minor changes.  The only substantial
  change in ALSA core is about the additional error handling in the
  compress-offload API.  Below are highlights:

   - Add the error propagating support in compress-offload API

   - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
     default mixer setup change ot turn off the loopback

   - Lots of updates for ASoC Intel drivers, mostly board support and
     bug fixing, and to the NAU8825 driver

   - Work on generalizing bits of simple-card to allow more code sharing
     with the Renesas rsrc-card (which can't use simple-card due to DPCM)

   - Removal of the Odroid X2 driver due to replacement with simple-card

   - Support for several new Mediatek platforms and associated boards

   - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
     Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
     and MAX98504, Realtek RT5514 and Wolfson WM8758"
