From 145eed48de278007f646b908fd70ac59d24ed81a Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 18 Jul 2022 09:23:17 +0200 Subject: fbdev: Remove conflicting devices on PCI bus Remove firmware devices on the PCI bus, by calling aperture_remove_conflicting_pci_devices() in the probe function of each related fbdev driver. iSo far, most of these drivers did not remove conflicting VESA or EFI devices, or outride failed for resource conflicts (i.e., matroxfb.) This must have been broken for quite some time.
