From 8dd26dc8fecab05aa92cd7f109f691c1283c5a13 Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Tue, 11 Nov 2014 15:45:31 -0700 Subject: [PATCH] PCI: xilinx: Save MSI controller in pci_sys_data Save MSI controller in pci_sys_data instead of assigning MSI controller pointer to every PCI bus in .add_bus().
