Subject: ALSA: hda - Enable widget power saving for Cirrus codecs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3e19fec33a5493f8a627a96ad3494d6c6dc2a624;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
