Subject[PATCH 66/88] hwmon: (sht15) Check return value of regulator_enable()
Date
3.5.7.8 -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.
