Hi Stephen, Lars
Thank you for your advice
This will fix it for most drivers, but there are a couple of drivers which use snd_soc_register_dais with 1 dai.
E.g. tegra/tegra20_ac97.c, sh/siu_dai.c, sh/hac.c, sh.ssi.c
I can check sh/* drivers. (I guess some of these are not used on sh, I'm not sure why...)
I believe this can be fixed simply by adjusting the relevant machine driver(s) to match whatever the new name is.
Any change to tegra20_ac97.c would only affect sound/soc/tegra/tegra_wm9712.c's struct tegra_wm9712_dai .cpu_dai_name field. I suspect the correct fix might be to just remove the assignment to .cpu_dai_name in tegra_wm9712.c; I think that because the .cpu_of_node field is always set by that driver, the value of .cpu_dai_name is never used? Anyway, if you fix tegra_wm9712.c in your patch, I hope that Lucas Stach can test it.
OK, I will try to fix it in v2 patch set
