Subject[PATCH v2 04/15] [media] lirc_dev: replace printk with pr_* or dev_*
Date
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
