commit 8a510a5c75261ba0ec39155326982aa786541e29 upstream.
It looks like in all cases 'struct vmw_connector_state' is used. But
only in stdu connectors, was atomic_{duplicate,destroy}_state() properly
subclassed. Leading to writes beyond the end of the allocated connector
state block and all sorts of fun memory corruption related crashes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
