Takashi Iwai 103f528d3b ASoC: Updates for v5.9 
The biggest changes here one again come from Mormioto-san who has
 continued his dilligent work cleaning up long standing issues in the
 APIs, it's particularly nice to see the transition from digital_mute()
 to mute_stream() finally completed. There's also been a lot of work on
 the x86 code again, this time a big focus has been on cleaning up some
 issues identified by various static tests, and on the Freescale systems.
 Otherwise the biggest thing has been a lot of driver additions:
 
  - Convert users of digital_mute() to mute_stream().
  - Simplify I/O helper functions.
  - Add a helper for getting the RTD from a substream.
  - Many, many fixes and cleanups to the x86 code.
  - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
    MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
    Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
    of the first phones I worked on!) and TI J721e EVM.
