Given that the other patch just landed and this is a straightforward
fix, I'm not doing the customary "delay" before landing and I've
pushed this to drm-misc-next:
14aed8ea48e2 drm/bridge: ps8640: Return NULL immediately when EDID read fail
If someone else had extra feedback on this it could always be handled
in a followon patch.
