If you are going to keep both DRM 4.0 and 4.1, please do it the same
way that Alan Cox did, to reduce the number of solutions to this
"problem".  The -ac kernels have, in drivers/char/Config.in

bool 'Direct Rendering Manager (XFree86 DRI support)' CONFIG_DRM

if [ "$CONFIG_DRM" = "y" ]; then
   bool '  Build drivers for new (XFree 4.1) DRM' CONFIG_DRM_NEW
   if [ "$CONFIG_DRM_NEW" = "y" ]; then
      source drivers/char/drm/Config.in
   else
      define_bool CONFIG_DRM_OLD y
      source drivers/char/drm-4.0/Config.in
   fi
fi

drivers/char/drm-4.0/ is a copy of the previous drivers/char/drm with
CONFIG_DRM_foo replaced by CONFIG_DRM40_foo.
