ALSA: cs4236: cs4232 and cs4236 driver merge to solve PnP BIOS detection
cs4232 and cs4236 driver merge to solve PnP BIOS detection. Also, the patch adds recognition if the chip is cs4236b+ or earlier part. This unifies drivers for both cs4232 and cs4236+ chips. It allows to use the PnP BIOS detection for the cs4236+ chips. Previously, only the snd-cs4232 could be detected by the PnP BIOS. The cs4232+ cards reports two separate PnP BIOS ids. The patch adds search for the second id to find out resources assigned to a control port. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
