The spacing check is unreachable for return statements
followed by an opening parentheses.
For example:
int foo(int bar, int baz)
{
return(bar+baz);
}
There should be an error emitted for a space between
return and the opening parentheses but checkpatch doesn't
emit one.
Fix the spacing check. Also add --fix option to
the check.
