Description
In the Linux kernel, the following vulnerability has been resolved:
drm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable()
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.
