Add an overriding exec_verb op to struct hdac_device so that the call via snd_hdac_exec_verb() can switch to a different route depending on the setup. The codec driver sets this field so that it can handle the errors or applying quirks appropriately. Furthermore, this mechanism will be used for smooth transition for the regmap support in later patches. Signed-off-by: Takashi Iwai <tiwai@suse.de>
