From 5594a54c520bd23ab9f2e098ccabf4fbebbbc7b9 Mon Sep 17 00:00:00 2001 From: Xiongfeng Wang Date: Tue, 21 Jul 2020 22:24:07 -0700 Subject: [PATCH] Input: psmouse - add a newline when printing 'proto' by sysfs [ Upstream commit 4aec14de3a15cf9789a0e19c847f164776f49473 ] When I cat parameter 'proto' by sysfs, it displays as follows. It's better to add a newline for easy reading. root@syzkaller:~# cat /sys/module/psmouse/parameters/proto autoroot@syzkaller:~# Signed-off-by: Xiongfeng Wang Link: https://lore.kernel.org/r/20200720073846.120724-1-wangxiongfeng2@huawei.com Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin --- drivers/input/mouse/psmouse-base.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/input/mouse/psmouse-base.c b/drivers/input/mouse/psmouse-base.c index 527ae0b9a191..0b4a3039f312 100644 --- a/drivers/input/mouse/psmouse-base.c +++ b/drivers/input/mouse/psmouse-base.c @@ -2042,7 +2042,7 @@ static int psmouse_get_maxproto(char *buffer, const struct kernel_param *kp) { int type = *((unsigned int *)kp->arg); - return sprintf(buffer, "%s", psmouse_protocol_by_type(type)->name); + return sprintf(buffer, "%s\n", psmouse_protocol_by_type(type)->name); } static int __init psmouse_init(void)
