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. Fixes: a73d511c4867 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20191213085111.22855-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
