 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:drm/vmwgfx: Unmap the surface before resetting it on a plane stateSwitch to a new plane state requires unreferencing of all held surfaces.In the work required for mob cursors the mapped surfaces started beingcached but the variable indicating whether the surface is currentlymapped was not being reset. This leads to crashes as the duplicatedstate, incorrectly, indicates the that surface is mapped even whenno surface is present. That s because after unreferencing the surfaceit s perfectly possible for the plane to be backed by a bo instead of asurface.Reset the surface mapped flag when unreferencing the plane state surfaceto fix null derefs in cleanup.
