ASoC: rt711/5682: check if bus is active before deferred jack detection
This patch takes a defensive programming and paranoid approach in case the parent device (SoundWire) is pm_runtime resumed but the rt711 device is not. In that case, during the attachment and initialization, a jack detection workqueue can be scheduled. Since the pm_runtime suspend routines will not be invoked, the sequence to cancel all deferred work is not executed, and the jack detection could happen after the bus stops operating, leading to a timeout. This patch applies the same solution to rt5682, based on the similarities between codec drivers. The race condition with rt5682 was not detected experimentally though.
