[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Veyon Solutions (veyon)]

The patch is also included in the mainline kernel since 5.4.66. Rebasing to 5.4.66 or newer should fix this issue. Without this patch, Windows VMs with attached virtualized Intel GPU (via mdev) always crashes as soon as the Intel graphics driver is being loaded in the guest. So please include this fix so GVT-g works properly with Ubuntu 20.04.
