When the input driver (like xf86-input-wacom) removes it's devices during a call to UnInit, the CloseDownDevices() cannot handle it. The "next" variable can become a pointer to freed memory. The patch introduces order-independent device freeing mechanism by remembering the already freed device ids. The devices can reorder any time during freeing. No device will be double-freed - if the removing failed for any reason; some implementations of DeleteInputDeviceRequest don't free the devices already.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
