[PATCH] cpuidle: make sysfs attributes sysdev class attributes

From: Rabin Vincent
Date: Tue Aug 05 2008 - 14:05:01 EST


These attributes are really sysdev class attributes. The incorrect
definition leads to an oops because of recent changes which make sysdev
attributes use a different prototype.

Based on Andi's f718cd4add5aea9d379faff92f162571e356cc5f ("sched: make
scheduler sysfs attributes sysdev class devices")
