Subject: [PATCH 1/1] ACPI: scan: Ignore Dell XPS 9320 camera graph port nodes

Ignore camera related graph port nodes on Dell XPS 9320. They data in BIOS
is buggy, just like it is for Dell XPS 9315. The corresponding software
nodes are created by the ipu-bridge.

Hi,

Could you test this and see whether it fixes the warning?

The camera might work with this change, too.
