From ae4fa5f4502bfa7e7f31fc99a1da41189422642d Mon Sep 17 00:00:00 2001 From: Duc Dang Date: Thu, 18 Jun 2015 11:45:39 -0700 Subject: PCI: xgene: Allow config access to Root Port even when link is down Previously, when a Root Port's link was down, we didn't allow config access to the Root Port, which meant that if the Root Port led to an empty slot, "lspci" didn't even show the Root Port. Allow config access to Root Port even when link is down.
