This is a note to let you know that I have just added a patch titled hwmon: (sht15) Check return value of regulator_enable() to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From b759601033bf8191e89df1c162fd142545914b11 Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@opensource.wolfsonmicro.com> Date: Sat, 2 Mar 2013 15:33:30 +0800 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.
