Subject: [PATCH] ALSA: hda/ca0132 - Keep power on during processing DSP response

Git-commit: 377bc0cfabce0244632dada19060839ced4e6949

Patch-mainline: v5.5-rc3

References: git-fixes

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.

Fixes: a73d511c4867 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection")
