[PATCH 3.11 109/128] hwmon: (emc2103) Fix return value

From: Luis Henriques
Date: Thu Jul 24 2014 - 05:56:08 EST


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

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

From: Sachin Kamat <sachin.kamat@xxxxxxxxxx>

commit 1a3abbd0b9a16e40fd4718f99896c437a193c0a1 upstream.

kstrtol() returns appropriate error values. Use those instead of
hardcoding. Silences several sparse messages of following type:
"why not propagate 'result' from kstrtol() instead of (-22)?"
