Date: Mon, 27 Nov 2017 11:57:57 -0500 From: Sinan Kaya <okaya@...eaurora.org> To: linux-pci@...r.kernel.org, timur@...eaurora.org Cc: linux-arm-msm@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, intel-gfx@...ts.freedesktop.org, Sinan Kaya <okaya@...eaurora.org>, Konrad Rzeszutek Wilk <konrad.wilk@...cle.com>, Boris Ostrovsky <boris.ostrovsky@...cle.com>, Juergen Gross <jgross@...e.com>, Bjorn Helgaas <bhelgaas@...gle.com>, xen-devel@...ts.xenproject.org (moderated list:XEN PCI SUBSYSTEM), linux-kernel@...r.kernel.org (open list) Subject: [PATCH V3 20/29] xen: 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. 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.
