ALSA: line6: Fix racy loopback handling The impulse and monitor handling in submit_audio_out_urb() isn't protected thus this can be racy with the capture stream handling. This patch extends the range to protect via each stream's spinlock (now the whole submit_audio_*_urb() are covered), and take the capture stream lock additionally for the impulse and monitor handling part.
