Hmm... this patch -- d86d1652ab13 ("apparmor: test: Remove some casts
which are no-longer required") -- has been sitting in the
apparmor-next branch since December, but there haven't been any
AppArmor pull requests since then.

If it's easier, I'm happy to redo this and send it in via the KUnit
tree (assuming it gets removed from apparmor-next). Otherwise, I guess
this'll just have to wait for the next AppArmor PR.
