From 9a97cd43f4ef62520a852b5a2348233b0f37455b Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Thu, 4 Apr 2013 20:01:23 +0200 Subject: MIPS/PCI: Implement pcibios_get_phb_of_node The of_node field of the device assigned to a PCI bus is used during scanning of the PCI bus. However on MIPS, the of_node field is assigned only after the bus has been scanned. Implement the architecture specific version of 'pcibios_get_phb_of_node'. Which ensures that the PCI driver core will initialize the of_node field before starting the scan. Also remove the local assignment of bus->dev.of_node, it is not needed after the patch.
