    drm/qxl: reapply cursor after resetting primary · 9428088c
    Ray Strode authored
    QXL associates mouse state with its primary plane.
    
    Destroying a primary plane and putting a new one in place has the side
    effect of destroying the cursor as well.
    
    This commit changes the driver to reapply the cursor any time a new
    primary is created. It achieves this by keeping a reference to the
    cursor bo on the qxl_crtc struct.
    
    This fix is very similar to
    
    commit 4532b241 ("drm/qxl: reapply cursor after SetCrtc calls")
    
    which got implicitly reverted as part of implementing the atomic
    modeset feature.
