Commit 9a61c54b9bff ("drm/rockchip: vop: group vop registers") seems to have unintentionally changed the defintion of this macro. Since it is unused, this was not spotted but any attempt to use it results in compilation errors. Revert to the previous definition.

This reverts commit 220df83a5394fbf7c1486ba7848794b7b351d598. Turns out drm_gem_dumb_map_offset really only worked for the dumb buffer case, so revert the name change.

2019-08-07drm/vgem: drop DRM_AUTH usage from the driverEmil Velikov1-2/+2
The authentication can be circumvented, by design, by using the render node. From the driver POV there is no distinction between primary and render nodes, thus we can drop the token.
