Subject: [PATCH] driver: probe: report power domain attach failure
Date: Sat, 30 Jul 2022 11:49:55 +0200	[thread overview]
Message-ID: <> (raw)

Power domains are attached before driver probe and non-existence of
power domain driver leads to permanent probe deferral without any
pointer as to why. Add a status message to make debugging easier.
