gcm_test_edid_func fails without udev
When gnome-desktop is built without udev, gnome_pnp_ids_get_pnp_id
returns 'Undefined':
https://gitlab.gnome.org/GNOME/gnome-desktop/-/blob/1acdc895650d9c624b3ea3674e09f9918d3959d1/libgnome-desktop/gnome-pnp-ids.c#L81
This causes the gcm_test_edid_func to fail. The attached patch works for me.test-udev.patch
