Subject: [PATCH 363/391] ASoC: codec: rt5640: Resolve failure to set DMIC
|
||
|
|
clock after playback
|
||
|
|
|
||
|
|
rt5640_set_dai_sysclk is called with freq == 0 when playback stops. This
|
||
|
|
causes DMIC setup code to fail. I2S interface doesn't need to be active
|
||
|
|
for codec to work, so don't clear rt5640->sysclk after rt5640_set_dai_sysclk
|
||
|
|
is called with freq == 0.
