Takashi Iwai 535df7f896 ALSA: line6: Fix racy access to midibuf ... commit 15b7a03205 upstream. There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. This could be a cause of KMSAN warning triggered by syzkaller below (so put as reported-by here). This patch protects the midibuf call of the former code path with a spinlock for avoiding the possible races.
