However, mute/micmute LED will clear codec's direct-complete flag by dpm_clear_superiors_direct_complete(). This doesn't play well with SOF driver. When its runtime resume is called for system suspend, hda_codec_jack_check() schedules jackpoll_work which uses snd_hdac_is_power_on() to check whether codec is suspended. Because the direct-complete path isn't taken, pm_runtime_disable() isn't called so snd_hdac_is_power_on() returns false and jackpoll continues to run, and snd_hda_power_up_pm() cannot power up an already suspended codec in multiple attempts, causes the long delay on system suspend: if (dev->power.direct_complete) { if (pm_runtime_status_suspended(dev)) { pm_runtime_disable(dev); if (pm_runtime_status_suspended(dev)) { pm_dev_dbg(dev, state, "direct-complete "); goto Complete; } pm_runtime_enable(dev); } dev->power.direct_complete = false; } When direct-complete path is taken, snd_hdac_is_power_on() returns true and hda_jackpoll_work() is skipped by accident. So this is still not correct. If we were to use snd_hdac_is_power_on() in system PM path, pm_runtime_status_suspended() should be used instead of pm_runtime_suspended(), otherwise pm_runtime_{enable,disable}() may change the outcome of snd_hdac_is_power_on(). Because devices suspend in reverse order (i.e. child first), it doesn't make much sense to resume an already suspended codec from audio controller. So avoid the issue by making sure jackpoll isn't used in system PM process.
