From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sinan Kaya Date: Wed, 22 Nov 2017 05:31:13 +0000 Subject: [PATCH 28/30] video: fbdev: riva: deprecate pci_get_bus_and_slot() Message-Id: <1511328675-21981-29-git-send-email-okaya@codeaurora.org> List-Id: References: <1511328675-21981-1-git-send-email-okaya@codeaurora.org> In-Reply-To: <1511328675-21981-1-git-send-email-okaya@codeaurora.org> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.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.
