From 8e7ca8ca5fd8a3242289105723c429733be8b73b Mon Sep 17 00:00:00 2001 From: Po Liu Date: Mon, 29 Aug 2016 15:26:58 +0800 Subject: PCI: xilinx: Relax device number checking to allow SR-IOV Previously we only allowed device 0 to be directly attached to the root port. But SR-IOV devices may use non-zero device numbers for VFs. Remove the restriction that only device 0 may be attached to a root port.
