Subject: [ 053/150] ALSA: hda - Disable runtime PM for Intel 5 Series/3400

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

------------------

From: Takashi Iwai <tiwai@...e.de>

commit 2c1350fdeaefefe1a149d3b083383409f43f0daa upstream.

We've got a regression report wrt the IRQ issue related with the
power-save on a Dell machine, and disabling runtime PM works around.
