[ALSA] hda-intel - Support multiple devices
It turned out that there can be multiple HD-audio devices on a single machine (e.g. on-board audio and HDMI on graphic cards), so we need to support multiple devices with snd-hda-intel driver. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
