Subject: [PATCH V3 04/29] ata: deprecate pci_get_bus_and_slot()
Date: Mon, 27 Nov 2017 11:57:41 -0500	[thread overview]
Message-ID: <1511801886-6753-5-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1511801886-6753-1-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 pci_get_domain_bus_and_slot() and extract the actual domain number
from the pdev passed in.
