[PATCH 3.14 046/228] hwmon: (emc1403) fix inverted store_hyst()

From: Greg Kroah-Hartman
Date: Wed Jun 04 2014 - 20:45:41 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Josef Gajdusek <atx@xxxxxxxx>

commit 17c048fc4bd95efea208a1920f169547d8588f1f upstream.

Attempts to set the hysteresis value to a temperature below the target
limit fails with "write error: Numerical result out of range" due to
an inverted comparison.
