From d46709094deb69a996bcde98f0a137561858c0fc Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 18 Sep 2018 19:44:29 +0200 Subject: [PATCH] staging: vboxvideo: Fold driver_load/unload into probe/remove functions Fold the driver_load / unload functions into the probe / remove functions now that we are no longer using the deprecated drm_get_pci_dev() mechanism.
