Subject: v4l2-compliance: add extra initial \n for error messages
Author:  Hans Verkuil <hans.verk...@cisco.com>
Date:    Thu Feb 8 14:16:09 2018 +0100

When walking through the interfaces and we cannot (yet) test an interface,
then add an initial \n to the message so the text looks like this:

--------------------------------------------------------------------------------

Unable to detect what device /dev/dvb/adapter1/demux0 is, skipping.

--------------------------------------------------------------------------------

instead of this:

--------------------------------------------------------------------------------
Unable to detect what device /dev/dvb/adapter1/demux0 is, skipping.

--------------------------------------------------------------------------------
