From 1acd14bfe9f191dcd80df99f80ec3880a706801e Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 6 Feb 2018 15:39:58 -0800 Subject: rapidio: return an error code only as a constant in two functions * Return an error code without storing it in an intermediate variable. * Delete the label "out" and local variable "rc" which became unnecessary with this refactoring.
