Subject: [PATCH] staging: sm750fb: Add void to function definition with no arguments
Date: Thu, 12 Mar 2015 01:11:00 +0900
Message-Id: <1426090260-9460-1-git-send-email-iskaranth@gmail.com>

Found by checkpatch.pl - ERROR: Bad function definition

A function with no arguments allows for variadic arguments. Add
void in between the empty parentheses to indicate that the function
takes no arguments.

changes made using coccinelle script:
@@
type T;
identifier f;
@@
T f(
+void
 ) {
...
}
