Subject: [PATCH] driver: probe: report power domain attach failure
Date: Sat, 30 Jul 2022 11:49:55 +0200 [thread overview]
Message-ID: <20220730094955.1768207-1-a.fatoum@pengutronix.de> (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.
