after entering psr
Can we please get rid of this somehow?

Updated frames get queued if self_refresh_aware is set when the
sink is in psr. To support bridge enable and avoid queuing of update
frames, reset the self_refresh_aware state after entering psr.

As I stated in v11's discussion, I do not like the way this change plays
with the self_refresh_aware. Please find another way to work around the
timing issue (let's probably continue the discussion back in v11).
Currently we are not able to reproduce the issue with KASAN enabled and minimum cpu frequency builds.
We can revisit this patch if it is reproduced in future. Meanwhile I think on handling it in a different way.
Can we not consider this patch for current merge?
Ack.
