3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ryan Mallon <[email protected]> commit bf9c05d5b6d19b3e4c9fe21047694e94f48db89b upstream. The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.
