Comment (by Richard Eisenberg <eir@…>):

 In [changeset:"55577a9130738932d022d442d0773ffd79d0945d/ghc" 55577a9/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="55577a9130738932d022d442d0773ffd79d0945d"
 Fix #11648.

 We now check that a CUSK is really a CUSK and issue an error if
 it isn't. This also involves more solving and zonking in
 kcHsTyVarBndrs, which was the outright bug reported in #11648.

 Test cases: polykinds/T11648{,b}

 This updates the haddock submodule.
