quilt complains about trailing whitespace when I build a YAFFS patch
against a kernel. I can't see any reason for this to be required, and
indeed I believe it'll be one of the things brought up when trying to
get included in mainline. So I've knocked up this patch that removes
trailing whitespace in the *.c and *.h files.
