From: Josef Gajdusek <atx@xxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
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.
