From: Takashi Iwai Date: Fri, 13 Dec 2019 08:51:09 +0000 (+0100) Subject: ALSA: hda/ca0132 - Keep power on during processing DSP response X-Git-Tag: v4.19.92~195 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f25b90f14b0b9a24d3afbd01ec88420f734e0633;p=thirdparty%2Fkernel%2Fstable.git ALSA: hda/ca0132 - Keep power on during processing DSP response commit 377bc0cfabce0244632dada19060839ced4e6949 upstream. We need to keep power on while processing the DSP response via unsol event. Each snd_hda_codec_read() call does the power management, so it should work normally, but still it's safer to keep the power up for the whole function.
