Takashi Iwai 89698ed5cc ALSA: hda: Use waitqueue for RIRB in HDA-core helper, too 
This patch implements the same logic that was done for the legacy
HD-audio controller driver by the commit 88452da92b ("ALSA: hda: Use
standard waitqueue for RIRB wakeup") to the HDA-core helper code,
too.  This makes snd_hdac_bus_get_response() waiting for the response
with bus->rirb_wq instead of polling when bus->polling is false.
It'll save both CPU time and response latency.
