Now most of the get_response handling became quite similar between HDA-core and legacy drivers, and the only differences are: - the handling of extra-long polling delay for some codecs - the debug message for the stalled communication and both are worth to share in the common code. This patch unifies the code into snd_hdac_bus_get_response(), and use this from the legacy get_response callback. It results in a good amount of code reduction in the end.
