Georges Basile Stavracas Neto de2aac7a3d src/seat-impl: Keep device variable alive for longer 
In meta_seat_impl_remove_virtual_input_device(), the 'device'
variable is first removed from MetaSeatImpl, then a "device
removed" event is generated with it.

The problem here is that, if this is the last reference of
'device', the removal from MetaSeatImpl will destroy it. Then
the freed variable will be used to create the "device removed"
event, which is a use-after-free situation.

Fix that by owning an extra ref to 'device' as long as the
function is executing. Do this by declaring a g_autoptr
variable with the extra ref. This g_autoptr variable is cleaned
up by the end of the function, which achieves the desired effect.

Spotted by Coverity.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
