Revision 744c67ffeb06f2d2493f4049ba0bd19698ce0adf authored by Hui Wang on 19 March 2019, 01:28:43 UTC, committed by Takashi Iwai on 19 March 2019, 05:52:19 UTC
The commit 3baffc4a84d7 (ALSA: hda/intel: Refactoring PM code) changed the behaviour of azx_resume(), it triggers the jackpoll_work after applying this commit. This change introduced a new issue, all codecs are runtime active after S3, and will not call runtime_suspend() automatically. The root cause is the jackpoll_work calls snd_hda_power_up/down_pm, and it calls up_pm before snd_hdac_enter_pm is called, while calls the down_pm in the middle of enter_pm and leave_pm is called. This makes the dev->power.usage_count unbalanced after S3. To fix it, let azx_resume() don't trigger jackpoll_work as before it did.
