Yeah, considered doing a backport patch to the kernel in openwrt. But I
concluded it was not worth the trouble, since we already have a working
module from the main repo.

If you do want to go the kernel patch route, it's a matter of figuring
out which patches you'll need to add to the backport series. Basically,
figure out which parts of the patch doesn't work, run git blame on the
file it is being applied to, and find the previous patch that changes
the context. Add that to you stack of backported patches, and rinse and
repeat until your series applies.

Your call whether that is less work that keeping your name on the
maintainer list until Openwrt naturally progresses past kernel 4.19 :)
