Subject: [PATCH 1/2] PCI: Make pcie_downstream_port() available outside of access.c
Date: Thu, 22 Aug 2019 11:55:52 +0300 [thread overview]
Message-ID: <20190822085553.62697-1-mika.westerberg@linux.intel.com> (raw)
This helper function is useful in other places where code needs to
determine whether the PCIe port is downstream so make it available
outside of access.c.
