Subject: Re: [PATCH] checkpatch: Warn on unnecessary void function return
 statements

My code has multiple exit lables:
void function(void)
{
	...

	if (err1)
		goto exit1;
	...
	if (err2)
		goto exit2;

	...
	return; /* Good return, no errors */
exit1:
	printk(err1);
	return;
exit2:
	printk(err2);
}

The single tabbed return was required to prevent the good return & err1 
messages cascading down. The extra exit label with a noop looks weird, 
but is passing checkpatch.pl --strict, so I will go with that, thanks.
