Subject: [PATCH] staging: media: atomisp: Remove unnecessary return statement
 in void function

Return statement at the end of a void function is useless.

The Coccinelle semantic patch used to make this change is as follows:
//<smpl>
@@
identifier f;
expression e;
@@
void f(...) {
<...
- return
  e;
  ...>
  }
//</smpl>
