yep I noticed already during the first problem, I couldn't even find
where the equivalent part of the code was located.

do not hesitate to add my tested-by on your current patchset if that helps.

* [PATCH V4 00/26] PCI: deprecate pci_get_bus_and_slot()
From: Sinan Kaya @ 2017-12-19 5:37 UTC (permalink / raw)
To: linux-arm-kernel
Deprecate pci_get_bus_and_slot() in favor of pci_get_domain_bus_and_slot()
in order to remove domain 0 assumptions in the kernel.
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.
Use pci_get_domain_bus_and_slot() with a domain number of 0 where we can't
extract the domain number. Other places, use the actual domain number from
the device.
Changes from v3:
* rebase to linux-next
* drop drm i915 as it is going through the drm tip
* commit summary cleanups

We don't search for the device in other domains than zero. This is because
on x86 platforms the BIOS executes only devices which are in domain 0.

* [PATCH V4 09/26] drm/nouveau: deprecate pci_get_bus_and_slot()
From: Sinan Kaya @ 2017-12-19 5:37 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1513661883-28662-1-git-send-email-okaya@codeaurora.org>
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.
Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().
Replace pci_get_bus_and_slot() with pci_get_domain_bus_and_slot()
and extract the domain number from
1. struct pci_dev
2. struct pci_dev through drm_device->pdev
3. struct pci_dev through fb->subdev->drm_device->pdev

* [PATCH V4 14/26] pch_gbe: deprecate pci_get_bus_and_slot()
From: Sinan Kaya @ 2017-12-19 5:37 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1513661883-28662-1-git-send-email-okaya@codeaurora.org>
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.
Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().
Use the domain information from pdev while calling into
pci_get_domain_bus_and_slot() function.
