ALSA: hda - define is_haswell() to check if a display audio codec is Haswell
To apply Haswell specific fixings, this patch defines is_haswell() to check whether a display audio codec is Haswell, to avoid explicitly checking Haswell vendor ID everywhere. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
