Subject: [PATCH v4 05/17] regulator: Assume probe deferral instead of missing regulator
Date: Wed, 16 Jan 2019 18:16:48 -0800	[thread overview]
Message-ID: <20190117021700.4443-6-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190117021700.4443-1-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
report it as probe deferral to give other, unprobed, drivers a chance
to resolve this.
