Subject: ALSA: firewire-motu: destroy stream data surely at failure of card initialization
From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>
commit dbd7396b4f24e0c3284fcc05f5def24f52c09884 upstream.
When failing sound card registration after initializing stream data, this
module leaves allocated data in stream data. This commit fixes the bug.
