From b1920c21102af1d22f27ce36378aa48d97a62bc0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 22 Nov 2013 12:43:25 +0100 Subject: [PATCH] ALSA: hda - Enable runtime PM on Panther Point Now we fixed the long-standing bugs of runtime PM, let's enable Panther Point again. The runtime PM was disabled in the HDMI codec driver due to the S3 issue, and this should have been fixed now.
