Subject: staging: rtl8723au: core: Remove uneeded return variable
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=038b70395a8a9b290bcd3aed292e4130a83944c7;p=deliverable%2Flinux.git

staging: rtl8723au: core: Remove uneeded return variable

This patch removes uneeded return variables, using only
'return _SUCCESS' instead.
It fixes the following warning detected by coccinelle:
Unneeded variable.

It was done using the following semantic patch:

@@
identifier ret;
type T;
expression e;
@@

-T ret = e;
 ... when != ret
     when strict
-return ret;
+return e;
