Subject: [PATCH 2/5] regulator: tps65910: use regmap accessors
Date: Sun, 27 Sep 2020 01:59:15 +0200	[thread overview]
Message-ID: <e82886d0f8f5131c9fccf2a17e3a15acce507d6f.1601164493.git.mirq-linux@rere.qmqm.pl> (raw)
In-Reply-To: <cover.1601164493.git.mirq-linux@rere.qmqm.pl>

Use regmap accessors directly for register manipulation - removing
one layer of abstraction.
