Commit 02f64b2d8605 ("drm/vram: drop DRM_VRAM_MM_FILE_OPERATIONS") dropped
DRM_VRAM_MM_FILE_OPERATIONS in preference for using DEFINE_DRM_GEM_OPS.

However, it was not dropped from the kernel docs.

Use DEFINE_DRM_GEM_OPS in the illustration on how to define a
struct file_operations for such a DRM driver and remove any reference
to DRM_VRAM_MM_FILE_OPERATIONS.

Thanks for the patch.
