Subject: [PATCH 1/1] PCI: xgene: Allow config access to Root Port even when link is down
Date: Thu, 18 Jun 2015 11:45:39 -0700 [thread overview]
Message-ID: <1434653139-14461-1-git-send-email-dhdang@apm.com> (raw)
Even if a Root Port's link is down, we should still be able to access the
Port's configuration space.
