[PATCH xserver 3/3] modesetting: Fall back to primary crtc for vblank for drawables on slave outputs

This fixes glxgears running at 1 fps when fully covering a slave-output and the modesetting driver is used for the master gpu. Reported-by: Peter Wu Signed-off-by: Hans de Goede --- hw/xfree86/drivers/modesetting/vblank.c | 22 ++ 1

Remove unused arguments from ms_covering_crtc, make it static as it is only used in vblank.c. While at it also change its first argument from a ScrnInfoPtr to a ScreenPtr, this makes the next patch in this patch-set cleaner. Signed-off-by: Hans de Goede ---
