Hmm, you submitted multiple patches doing the similar things but the
error messages are handled completely differently in both cases.
Please make them consistent.

... and above all:

> - snd_card_register(line6->card);
> + if (snd_card_register(line6->card))
> + pr_warn("Failed to register ALSA card.\n");

This error message is almost useless. Better to use dev_*() variant.
