We have met a deadlock issue on our device when resuming.
After applying this patch which is picked from mainline, issue solved.
We'd like to backport to 5.15.y and could you help to review? thanks.

[ Upstream commit 3e999770ac1c7c31a70685dd5b88e89473509e9c ]

For obvious reasons (and as per the documentation), we can't take
commits that are not also in all newer kernel releases, otherwise you
would have a regression if you moved to a newer kernel, right?

Please submit a series for all affected releases if you wish for a patch
to be applied to the trees.

thanks,
