When disabling overlay plane in mxsfb_plane_overlay_atomic_update(), overlay plane's framebuffer pointer is NULL. So, dereferencing it would cause a kernel Oops(NULL pointer dereferencing). Fix the issue by disabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.Fixes: cb285a5348e7 ("drm: mxsfb: Replace mxsfb_get_fb_paddr() with drm_fb_cma_get_gem_addr()") Signed-off-by: Liu Ying <victor....@nxp.com>
