By any chance, have you tried sending the patch upstream? If not, that
would be nice a nice thing to do. As a small nit, could you also add an
“Upstream-Status” tag line next to the “Signed-off-by” one and resubmit
the patch?
BTW, I have noticed that the manual does NOT mention anything about the
“Upstream-Status” tag at all. Probably it would be a good idea to add
some notes about this.
