Subject: ALSA: line6: fix check on snd_card_register
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=02cc53e223d498010de5f114d72c11a2d55118e8;p=linux.git

ALSA: line6: fix check on snd_card_register

The fix checks if snd_card_register() fails, and if so logs the error
via dev_err() consistent with other patches.
