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}() changes the result of snd_hdac_is_power_on(). Because devices suspend in reverse order (i.e. child first), it doesn't make much sense to resume already suspended codec from audio controller. So instead of using pm_runtime_status_suspended(), the better approach here is to make sure jackpoll isn't used in system PM process.
