-/**
- * drm_gem_simple_display_pipe_prepare_fb - prepare_fb helper for &drm_simple_display_pipe
- * @pipe: Simple display pipe
- * @plane_state: Plane state
- *
- * This function uses drm_gem_plane_helper_prepare_fb() to extract the fences
- * from &drm_gem_object.resv and attaches them to the plane state for the atomic
- * helper to wait on. This is necessary to correctly implement implicit
- * synchronization for any buffers shared as a struct &dma_buf. Drivers can use
- * this as their &drm_simple_display_pipe_funcs.prepare_fb callback.
- *
- * See drm_gem_plane_helper_prepare_fb() for a discussion of implicit and
- * explicit fencing in atomic modeset updates.
