media: stkwebcam: Use more common logging styles
Convert STK_<LEVEL> to pr_<level> to use the typical kernel logging. Add a define for pr_fmt. No change in logging output. Miscellanea: o Remove now unused PREFIX and STK_<LEVEL> macros o Realign arguments o Use pr_<level>_ratelimited o Add a few missing newlines to formats Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
