Sat Dec 31 14:04:59 PST 2016


From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 31 Dec 2016 22:00:28 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: quoted string split across lines

* Thus fix the affected source code places.

* Improve indentation for passed parameters.
