Subject: [PATCH v2 06/18] regulator: Add primitive support for deferred probe
Date: Fri, 11 Jan 2019 21:55:12 -0800	[thread overview]
Message-ID: <20190112055524.7733-7-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190112055524.7733-1-andrew.smirnov@gmail.com>

Don't report requested regulator (via of_regulator_get()) as
non-existent if said regulator is missing from regulator list. Instead
rely on driver_deferred_probe_check_state() to properly declare
regulator as such after all of the initcalls were done and no further
missing dependencies could be resolved.
