Maintainers don't maintain the functionality, they maintain the source
code. They fix conflicts and order patches. On that line, not Cc-ing
maintainers when you change the code of the drivers they maintain makes
their lives all more ... "entertaining".

And I would argue that the patch does introduce functional changes, as
it removes the clip rectangle from drm_atomic_helper_check_plane_state()'s
list of parameters. It does change all the users of it, too, I agree, but
not for people that have drivers not yet upstreamed (and they start to wonder
how one driver compiles and other fails when they were supposed to have the
same code inside :) )
