from stable-v6.6.58
commit fd6e2af79a947e909c72b09f1ce3175f381067ef

--------------------------------

commit 164cd0e077a18d6208523c82b102c98c77fdd51f upstream.

The cached version avoids redundant commands to the codec, improving
stability and reducing unnecessary operations. This change ensures
better power management and reliable restoration of pin configurations,
especially after hibernation (S4) and other power transitions.
