From 3fac031460e31b5ba1da578bf43f81a9c7a751cc Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Wed, 6 Jul 2016 06:01:16 -0300 Subject: [PATCH] [media] lirc_dev: replace printk with pr_* or dev_* This patch mutes also all the checkpatch warnings related to printk. Reword all the printouts so that the string doesn't need to be split, which fixes the following checkpatch warning: WARNING: quoted string split across lines Signed-off-by: Andi Shyti Signed-off-by: Mauro Carvalho Chehab --- drivers/media/rc/lirc_dev.c | 79 ++++++++++++++++--------------------- 1 file changed, 34 insertions(+), 45 deletions(-) diff --git a/drivers/media/rc/lirc_dev.c b/drivers/media/rc/lirc_dev.c index 9f20f94a31ae..59f4c93cccc4 100644 --- a/drivers/media/rc/lirc_dev.c +++ b/drivers/media/rc/lirc_dev.c @@ -19,6 +19,8 @@ * */ +#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt + #include #include #include @@ -240,59 +242,51 @@ static int lirc_allocate_driver(struct lirc_driver *d) int err;
