* struct vmw_kms_dirty - closure structure for the vmw_kms_helper_dirty
* function.
*
* @fifo_commit: Callback that is called once for each display unit after
* all clip rects. This function must commit the fifo space reserved by the
* helper. Set up by the caller.
* @clip: Callback that is called for each cliprect on each display unit.
* Set up by the caller.
* @fifo_reserve_size: Fifo size that the helper should try to allocat for
* each display unit. Set up by the caller.
* @dev_priv: Pointer to the device private. Set up by the helper.
* @unit: The current display unit. Set up by the helper before a call to @clip.
* @cmd: The allocated fifo space. Set up by the helper before the first @clip
* call.
* @num_hits: Number of clip rect commands for this display unit.
* Cleared by the helper before the first @clip call. Updated by the @clip
* callback.
* @fb_x: Clip rect left side in framebuffer coordinates.
* @fb_y: Clip rect right side in framebuffer coordinates.
* @unit_x1: Clip rect left side in crtc coordinates.
* @unit_y1: Clip rect top side in crtc coordinates.
* @unit_x2: Clip rect right side in crtc coordinates.
* @unit_y2: Clip rect bottom side in crtc coordinates.
*
* The clip rect coordinates are updated by the helper for each @clip call.
* Note that this may be derived from if more info needs to be passed between
* helper caller and helper callbacks.
