Subject: [PATCH] regulator: Simplify regulator_bulk_get and regulator_bulk_enable error paths
Date: Mon, 20 Feb 2012 10:32:16 +0800 [thread overview]
Message-ID: <1329705136.3189.1.camel@phoenix> (raw)
Start unwind from the point the error happens instead of iterating over all
consumers, then unwind code can be simpler.
