How did you generate this one? The white-space issue is gone, but now
it's a "p0" patch again (without the root directory in the paths) so
checkpatch complains and it does not apply using git am (with the normal
settings anyway).

Again, I can fix this up unless you prefer to respin. We have until the
end of the merge window to get it right. :)
