Subject: [PATCH 5/7] rapidio: Delete an unnecessary variable initialisation in
 three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 15 Dec 2017 10:21:15 +0100

The local variable "rc" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
