Staging: speakup: Remove unused variable
Author: Haneen Mohammed <hamohammed.sa@gmail.com>
This patch removes variable that was used to store only the return value of a function call.
The issue was detected and resolved using the following coccinelle script:
@@
expression ret;
identifier f;
@@
-ret =
+return
f(...);
-return ret;
