Subject: [PATCH 08/18] regulator: stpmic1: fix registering missed regulators
Date: Mon, 28 Sep 2020 17:50:31 +0200	[thread overview]
Message-ID: <20200928155041.32649-9-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200928155041.32649-1-m.felsch@pengutronix.de>

The dts regulators subnode can be incomplete e.g. if the pre-programmed
values are valid and shouldn't be changed. Missing regulator nodes are
indicated by "of_regulator_match->of_node == NULL". Take missing
regulators into account and register only existing ones.
