Hi,

I have noticed Runtime PM usage count underflow on my Chromebook (12th
Gen Intel(R) Core(TM) i3-1215U) running vanilla v6.1-rc2:

[ 7.558178] max98373 i2c-MX98373:00: Runtime PM usage count underflow!
[ 7.558188] max98373 i2c-MX98373:01: Runtime PM usage count underflow!
[ 7.558206] snd-soc-dummy snd-soc-dummy: Runtime PM usage count underflow!
[ 7.558421] snd-soc-dummy snd-soc-dummy: Runtime PM usage count underflow!

[PATCH] Revert "ASoC: soc-component: using pm_runtime_resume_and_get
