drm/nouveau: deprecate pci_get_bus_and_slot()
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 Signed-off-by: Sinan Kaya <okaya@codeaurora.org> Signed-off-by: Bjorn Helgaas <helgaas@kernel.org>
