Subject: [PATCH V2 01/29] alpha/PCI: deprecate pci_get_bus_and_slot()
Date: Wed, 22 Nov 2017 17:48:56 -0500	[thread overview]
Message-ID: <1511390964-9979-2-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1511390964-9979-1-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.

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.
