From cf2b94daab9f3d21b0a393bef91292622f6a8ca4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 15 Mar 2012 15:17:12 -0700 Subject: drivers/video/backlight/s6e63m0.c: fix corruption storing gamma mode strict_strtoul() writes a long but ->gamma_mode only has space to store an int, so on 64 bit systems we end up scribbling over ->gamma_table_count as well. I've changed it to use kstrtouint() instead.
