[alsa-devel] [PATCH] ASoC: Tegra and i.MX are mutually exclusive

[Arnd Bergmann]

Both Tegra and i.MX provide ac97 operations, which can only
exist once in the kernel. They can both be built as loadable
modules (only one of them needs to be loaded anyway), but we
have to disallow enabling them both as built-in.
