Subject: [PATCH v2 04/15] [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
