3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 087c2e3b4e062573dbbc8a50b9208992e3768dcf upstream.
Since the transition to the generic parser, the actual routes used there don't match always with the assumed static paths in some set_widgets_power_state callbacks. This results in the wrong power setup in the end. As a temporary workaround, we need to disable the calls together with the non-functional dynamic power control enum.
