From 85c6e4fabb4c26e5cd8a024415ed2f5bcdd578db Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 6 Jun 2013 18:48:50 +1000 Subject: pci: Add root bus argument to pci_get_bus_devfn() pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus * and device/function number within that bus. Currently it assumes it is working on an address under the primary PCI root bus. This patch extends it to allow the caller to specify a root bus. This might seem a little odd since the supplied address can (theoretically) include a PCI domain number. However, attempting to use a non-zero domain number there is currently an error, so that shouldn't really cause problems. Signed-off-by: David Gibson Signed-off-by: Michael S.
