this seems like a good change. It's a bit unfortunate this logic is not 
yet shared and SOF uses the variant in snd_hdac_bus_get_response() -- that 
would need similar treatment. I can make a matching change there and see 
how this fairs in SOF CI. But basic tests with snd-hda-intel on a few 
systems didn't reveal anything odd and code seems correct.
