Subject: [PATCH v1 2/2] pinctrl: baytrail: Convert to use devm_*()
Date: Tue, 10 Jan 2017 22:11:39 +0200	[thread overview]
Message-ID: <20170110201139.129737-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170110201139.129737-1-andriy.shevchenko@linux.intel.com>

This simplifies error handling and allows us to drop error path handlers
completely.
