From 3e19fec33a5493f8a627a96ad3494d6c6dc2a624 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 15 Oct 2015 11:17:09 +0200 Subject: [PATCH] ALSA: hda - Enable widget power saving for Cirrus codecs Cirrus codecs have also fine power controls on each widget, thus it gets benefit from the recent widget power-saving feature. As we haven't seen any obvious regressions with tests on some MacBooks, let's try to enable it.
