Joe, I confirm the error went away. Looks like a bug in checkpatch.pl
to me. I tried a number of combinations of things and it didn't
complain about several things it should have. I did try a few other
things to make sure it was still finding problems like brace placement
and leading spaces, but it looks like the blank line checking code isn't
working. This is on 4.0, so maybe it has been fixed since then. Scott,
what kernel version are you using?
