SubjectRe: [PATCH] staging: media: lirc: lirc_zilog.c: adjust debug messages

Usually you would like to send this as two separate patches because
replacing a debug message is way different than removing some code. It
should look like:

PATCH 0/2 staging: media: adjust debug messages
PATCH 1/2 staging: media: replace dev_err...
PATCH 2/2 staging: media: remove debug message..

The lirc_zilog.c is not necessary in the topic line, as this can be seen
from the diff.

What is the reason behind this change? What would happen if the
filep->private_data is NULL? Are the callers of this function aware that
it will not return ENODEV anymore?
