Steps to reproduce:
I was playing with wine and some random games. I don't know if I can reproduce it.

# CONFIG_SND_DEBUG is not set

If I understand correctly, even without CONFIG_SND_DEBUG it should handle bogus
values gracefully. Looks like it's not checking the input enough (maybe in
snd_pcm_hw_params_user).
