[PATCH 3.12 89/91] PM / devfreq: Fix incorrect type issue.

[Jiri Slaby]

From: Xiaolong Ye <yexl@xxxxxxxxxxx>

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

===============

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.
