Change looks fine:

Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

Are you looking for us to merge or merge through another tree?

If us, did the base patch always enabling PREEMPT_COUNT go into 5.9 or is
it heading to 5.10? We can queue this earliest for 5.11 as drm-next closed
for 5.10 at week of -rc5.

Regards, Joonas
