   4 Subject: [PATCH] ASoC: fsl_sai: Mark cache dirty at resume
   5
   6 This is needed so that at resume will restore the
   7 correct SAI registers.
   8
   9 Looks like the call to regcache_mark_dirty was missed when
  10 porting commit 760bd6187413e37c8 ("MLK-15960-2: ASoC: fsl_sai: refine
  11 the pm runtime function")
