Hi, Tomeu

after apply your NPU patches:

VIM3 failed to start gnome/gdm3 wayland session.

before:

VIM3:~$ ls /dev/dri/by-path/ -l
total 0
lrwxrwxrwx 1 root root  8 Dec 27 04:06 platform-ff900000.vpu-card -> ../card0
lrwxrwxrwx 1 root root  8 Dec 27 04:06 platform-ffe40000.gpu-card -> ../card1
lrwxrwxrwx 1 root root 13 Dec 27 04:06 platform-ffe40000.gpu-render -> ../renderD128

after:

VIM3:~$ ls /dev/dri/by-path/ -l

lrwxrwxrwx 1 root root  8 Dec 27 04:10 platform-etnaviv-card -> ../card0

the fail log:
