[alsa-devel] [PATCH] ASoC: soc-ac97: replace codec to component
From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
codec will be replaced to component soon. AC97 is codec related feature now. Thus this patch replaces codec to component on AC97.
To keep compatibility, previous snd_soc_xxx_ac97_codec() is now defined as macro to convert snd_soc_xxx_ac97_component().
Signed-off-by: Kuninori Morimoto kuninori.morimoto.gx@renesas.com --- - I have no AC97 board. Compile test only had done.

Given that there's Robert's big AC'97 refactoring patch in review right now I don't want to apply this and cause him to have to rebase, I'm expecting this version to go in.

OK I see. No problem I will repost this patch after that.
