Subject: [PATCH v3 01/17] regulator: Convert drivers to use struct regulator_desc
Date: Tue, 15 Jan 2019 12:25:45 -0800	[thread overview]
Message-ID: <20190115202601.24831-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190115202601.24831-1-andrew.smirnov@gmail.com>

To simplify porting kernel code, port a very basic struct
regulator_desc and convert all of the code to use it.
