From: Colin Ian King <colin.i.king@gmail.com> stable inclusion from stable-v5.10.89 commit 69e492161c7b563684caf0fad01382279c065213 bugzilla: 186140 https://gitee.com/openeuler/kernel/issues/I4S8HA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 2dee54b289fbc810669a1b2b8a0887fa1c9a14d7 upstream. 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> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Chen Jun <chenjun102@huawei.com> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> --- sound/drivers/opl3/opl3_midi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/drivers/opl3/opl3_midi.c b/sound/drivers/opl3/opl3_midi.c index eb23c55323ae..a2583a30c45a 100644 --- a/sound/drivers/opl3/opl3_midi.c +++ b/sound/drivers/opl3/opl3_midi.c @@ -398,7 +398,7 @@ void snd_opl3_note_on(void *p, int note, int vel, struct snd_midi_channel *chan) } if (instr_4op) { vp2 = &opl3->voices[voice + 3]; - if (vp->state > 0) { + if (vp2->state > 0) { opl3_reg = reg_side | (OPL3_REG_KEYON_BLOCK + voice_offset + 3); reg_val = vp->keyon_reg & ~OPL3_KEYON_BIT; -- 2.20.1
