Subject: [PATCH 3.10 030/319] PM / devfreq: Fix incorrect type issue.
From: Xiaolong Ye <yexl@...vell.com>
commit 5f25f066f75a67835abb5e400471a27abd09395b upstream
time_in_state in struct devfreq is defined as unsigned long, so
devm_kzalloc should use sizeof(unsigned long) as argument instead
of sizeof(unsigned int), otherwise it will cause unexpected result
in 64bit system.
