While this isn't fatal (the uninitialized parameter is also unused :),
it's not a mistake we want to live on in an LTS. Also there are other
problems with the patch reported by 'gbp pq import' so we should redo
this using the correct upstream patches:

[regression] GNOME 46/47 dropped support for Xilinx Mali graphics

Bug description:
[ Impact ]
Xilinx Mali support was originally written for GNOME 42 but it has
bitrotted since then. We need to apply a few fixes to get it working
again in GNOME 46 (Ubuntu 24.04 LTS) and later:
* https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4019 or
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4021
* https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4036
[ Test Plan ]
1. Log into an Ubuntu (GNOME + Wayland) session on Xilinx hardware.
2. Verify you can log in, there are no obvious rendering failures and that it
really is a Wayland session (environment XDG_SESSION_TYPE=wayland and
WAYLAND_DISPLAY=wayland-0).
[ Where problems could occur ]
The Mutter/GNOME startup procedure had to be modified for this fix as well as
some texture format parameters. So there is a small risk to:
(a) The ability of any machine to log into a Wayland session; and
(b) Rendering correctness once logged in.
