From: Greg KH <[email protected]> 3.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Hunt Xu <[email protected]> commit 5ab3633d6907018b0b830a720e877c3884d679c3 upstream. Commit 0136db586c028f71e7cc21cc183064ff0d5919c8 merges rc6 information into the power group. However, when compiled with CONFIG_PM not set, modprobing i915 would taint since power_group_name is defined as NULL. This patch makes these rc6 in sysfs functions conditional upon the definition of the CONFIG_PM macro to avoid the above-mentioned problem.
