[PATCH v2] Input: convert obsolete strict_strtox to kstrtox

From: JJ Ding
Date: Mon Nov 07 2011 - 06:57:22 EST

From: JJ Ding <dgdunix@xxxxxxxxx>

With commit 67d0a0754455f89ef3946946159d8ec9e45ce33a we mark strict_strtox
as obsolete. Convert all remaining such uses in drivers/input/.

Also change the data type from long to int as Dmitry sugguests, we now have
kstrtouint which suits these uses better.

Signed-off-by: JJ Ding <dgdunix@xxxxxxxxx>
