Subject: [ 11/21] hwmon: (sht15) Check return value of regulator_enable()
Date: Tue, 12 Mar 2013 15:44:13 -0700 [thread overview]
Message-ID: <20130312223246.431610777@linuxfoundation.org> (raw)
In-Reply-To: <20130312223245.109098379@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
commit 3e78080f81481aa8340374d5a37ae033c1cf4272 upstream.
Not having power is a pretty serious error so check that we are able to
enable the supply and error out if we can't.
