Subject: [PATCH 15/18] [media] RedRat3: Delete two variables in
 redrat3_set_timeout()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 13 Oct 2016 15:40:33 +0200

* Use the data structure members "dev" and "udev" directly
  without assigning them to intermediate variables.
  Thus delete the extra variable definitions at the beginning.

* Fix indentation for the parameters of two function calls.
