Merge tag 'v5.4.49' into 5.4-2.1.x-imx
This is the 5.4.49 stable release
Conflicts (manual resolve, NXP version taken):
sound/soc/fsl/fsl_esai.c
Commit 53057bd4ac84f upstream addresses the problem of endless isr in
case if exception interrupt is enabled and tasklet is scheduled. Since
NXP implementation has tasklet removed with commit 2bbe95fe6c0dd,
upstream fix does not match the main implementation, hence we keep the
NXP version here.
