From 377bc0cfabce0244632dada19060839ced4e6949 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 13 Dec 2019 09:51:09 +0100 Subject: ALSA: hda/ca0132 - Keep power on during processing DSP response 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.
