staging: dgnc: Merge assignment with return

Instead of storing the return value of a function call into a variable and
then returning it, we can club the two into a single return statement. This
change was made using the following semantic patch by Coccinelle:

@@
local idexpression ret;
expression e;
@@

-ret =
+return
     e;
-return ret;
