3.13.11.6 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Peter Meerwald <pme...@pmeerw.net>
commit 9b2a4d35a6ceaf217be61ed8eb3c16986244f640 upstream.
val2 should be zero
This will make no difference for correct inputs but will reject
incorrect ones with a decimal part in the value written to the sysfs
interface.
