-Subject: [PATCH 556/806] soc: bcm: bcm2835-pm: Fix error paths of
- initialization.
-
-The clock driver may probe after ours and so we need to pass the
--EPROBE_DEFER out.  Fix the other error path while we're here.
-
-v2: Use dom->name instead of dom->gov as the flag for initialized
-    domains, since we aren't setting up a governor.  Make sure to
-    clear ->clk when no clk is present in the DT.
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-Fixes: 670c672608a1 ("soc: bcm: bcm2835-pm: Add support for power domains under a new binding.")
