[alsa-devel] [PATCH] uda134x: properly free allocated memory if uda134x_soc_probe fail with unknown codec type

[Axel Lin]

If uda134x_soc_probe fail with unknown codec type, it should properly free
allocated memory before return -EINVAL.

This case won't be executed in current implementation because there is a
model checking in the begin of uda134x_soc_probe.
But since the code is there, I think it's good to make it correct.
Otherwise, we can simply remove the default case.
