From 352af7d4dd90bac3640ad2383e4e9f332d3a4537 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 11 Feb 2013 08:46:10 +0100 Subject: [PATCH] ARM: 7648/1: pci: Allow passing per-controller private data In order to allow drivers to specify private data for each controller, this commit adds a private_data field to the struct hw_pci. This field is an array of nr_controllers pointers that will be used to initialize the private_data field of the corresponding controller's pci_sys_data structure.
