[Mesa-dev] [PATCH 2/4] radeon, r200: remove support for UMS radeon DRM module

[Emil Velikov]

As mentioned by Michel Dänzer
 "FWIW though, any code which is specific to radeon DRM major version 1
  can be removed, because that's the UMS major version."

and Marek Olšák
 "major != 2" can't occur. You don't have to check the major version at
  all and you can just assume it's always 2."
