ALSA: drivers: opl3: Fix incorrect use of vp->state
Static analysis with scan-build has found an assignment to vp2 that is never used. It seems that the check on vp->state > 0 should be actually on vp2->state instead. Fix this. 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> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20211212172025.470367-1-colin.i.king@gmail.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
