backport/main does not compile against ubuntu kernel 6.8.0-43.43 (and possibly newer)

driver compilation fails with:

possibly because of this commit: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble/commit/?h=master-next&id=263efcb86dc38ca8cfcae8846bfa1cb4a1bc0c4c

currently 6.8.0-44.44 is in proposed (see https://launchpad.net/ubuntu/noble/+source/linux)

(noticed during compilation agains proxmox-kernel-6.8.12-1-pve which is based on 6.8.0-43.43)
