Hmm. That original patch looks obviously buggy: in kobject_cleanup()
it would end up doing "kobject_put(parent)" regardless of whether it
had actually done __kobject_del() or not.

That _could_ have been intentional, but considering the commit
message, it clearly wasn't in this case.  It might be worth re-trying
to the commit, just with that fixed.

Btw, when you end up reverting a patch that was already the top patch,
you might as well just remove it entirely from that tree instead (ie
"git reset --hard HEAD^" instead of "git revert HEAD").

Unless somebody else uses your branches and you are afraid that the
non-reverted commit escaped out in the wild that way?
