[ALSA] isa_bus: es1688
es1688: port to isa_bus infrastructure. very slight reorganization of the auto-probe code to be a bit easier on the eye (if not the senses). Signed-off-by: Rene Herman <rene.herman@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
