| Subject: ALSA: hda/ca0132 - Keep power on during processing DSP response |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| 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. |
| |
| Fixes: a73d511c4867 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection") |
