[ALSA] ASoC AC97 device reg bugfix
This patch fixes a bug whereby AC97 bus device data was being clobbered when AC97 codecs using the generic ac97_codec.c driver were being registered. Codecs that didn't use the generic driver were unaffected (e.g. WM9712, WM9713). Changes:- o Add new AC97 codec class for custom (or need bus dev registration) AC97 codecs. o Only register/deregister this custom codec device with the AC97 bus. The generic AC97 driver already does this for generic codec devices. This may be related to bug #3038 :- https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3038 Signed-off-by: Liam Girdwood <lg@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
