pushing to haddock

[Simon Peyton Jones]

I'm trying desperately to follow the instructions on https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/Git/Submodules for how to update haddock to follow a small change to GHC.
I've checked out the haddock master, made my patch, and want to push to haddock. But my push is rejected for an inscrutable reason:

git status

# On branch master

# Your branch is ahead of 'origin/master' by 1 commit.

#

nothing to commit (working directory clean)

error: failed to push some refs to 'ssh://git@ghc.haskell.org/haddock.git'

What do I do now?
Presumably once that's done I include the change to utils/haddock in my patch to HEAD, correct?
Getting to Haddock HEAD added 12 new patches on the haddock branch so I suppose they'll be included too. I don't know whether that is good or bad.
help!
