??
$ grep nonatomic sound/soc/intel/boards/cht_bsw_max98090_ti.c
.nonatomic = true,
.nonatomic = true,

For the record it is must have for all of the drivers :)
$ grep -L nonatomic sound/soc/intel/boards/*.c
sound/soc/intel/boards/bdw-rt5677.c
sound/soc/intel/boards/broadwell.c
sound/soc/intel/boards/byt-max98090.c
sound/soc/intel/boards/byt-rt5640.c
sound/soc/intel/boards/haswell.c
sound/soc/intel/boards/mfld_machine.c
So we should add the remaining one byt-max98090.c as Takashi fixed
byt-rt5640.c one. I will send the patch for this one.
