This dates back to 2002, I found the offending commit from the git history git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git, commit 91e39521bbf6 ("[PATCH] ALSA patch for 2.5.4") Signed-off-by: Colin Ian King <colin.i.king@gmail.com> --- sound/drivers/opl3/opl3_midi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
