Subject: [PATCH] hwmon: (sht15) Check return value of regulator_enable()

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.

[bwh: Backported to 3.2: driver does not use the devm API to manage
 memory, so goto err_free_data rather than returning on error]
