staging: Remove unnecessary semicolons when while (foo) {...};

Done via perl script:

$ cat remove_semi_while.pl
my $match_balanced_parentheses = qr/(\((?:[^\(\)]++|(?-1))*\))/;
my $match_balanced_braces      = qr/(\{(?:[^\{\}]++|(?-1))*\})/;

foreach my $file (@ARGV) {
    my $f;
    my $text;
    my $oldtext;

    next if ((-d $file));

    open($f, '<', $file)
	or die "$P: Can't open $file for read\n";
    $oldtext = do { local($/) ; <$f> };
    close($f);

    next if ($oldtext eq "");

    $text = $oldtext;

    my $count = 0;
    do {
	$count = 0;
	$count += $text =~ s@\b(while\s*${match_balanced_parentheses}\s*)${match_balanced_braces}\s*;@"$1$3"@egx;
    } while ($count > 0);

    if ($text ne $oldtext) {
	my $newfile = $file;

	open($f, '>', $newfile)
	    or die "$P: Can't open $newfile for write\n";
	print $f $text;
	close($f);
    }
}

$

One false positive removed.
