Subject: simplify-cleanup_workqueue_thread-fix
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
we now have:
int foo(..)
{
if (expr1) {
...
return x;
} else {
...
return y;
}
}
but some versions of gcc have a habit of (wrongly) warning about the failure
to return anything from a non-void-returning function.
Fiddle the code to avoid that.
