I didn't submit a patch, I suggested a possible improvement to
your patch.  If you agree with it, you could resubmit.

Seems sensible.

Mike, checkpatch does already allow a single space to precede
a label but there's a conflict between the leading spaces test
and this test below it, so something like your patch is useful.

----------------
#goto labels aren't indented, allow a single space however
		if ($line=~/^.\s+[A-Za-z\d_]+:(?![0-9]+)/ and
		   !($line=~/^. [A-Za-z\d_]+:/) and !($line=~/^.\s+default:/)) {
			WARN("labels should not be indented\n" . $herecurr);
		}
----------------

The leading space test may be overly noisy.
Maybe Andy can fix it a different way.

About 1% (~500) of the labels in the kernel source tree use
leading tabs.  I think that label style is harder for me to
visually scan and find, but it's probably not code I'd change
just for conformity.
