[alsa-devel] [PATCH] 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 :-

Manuel, can you try this on SH & Au1x00.

Thanks
