Subject: [PATCH] ASoC: fsl_sai: Mark cache dirty at resume
|
|
|
|
|
|
|
|
|
|
This is needed so that at resume will restore the
|
|
|
|
|
correct SAI registers.
|
|
|
|
|
|
|
|
|
|
Looks like the call to regcache_mark_dirty was missed when
|
|
|
|
|
porting commit 760bd6187413e37c8 ("MLK-15960-2: ASoC: fsl_sai: refine
|
|
|
|
|
the pm runtime function")
|
|
|
|
|
|
|
|
