From 7e16fd6df178d3395d32c7d325df69062ea6e024 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 6 Jul 2016 10:06:00 -0600 Subject: [PATCH] PCI: Bind DPC to Root Ports as well as Downstream Ports PCIe port type values are not flags, so OR'ing them is not correct. Previously the result was equivalent to PCIe Downstream Ports, so we were missing binding to DPC-capable Root Ports. Change the type to 'any' so we can bind to both port types. While this will cause the code to check Upstream Ports, the driver won't claim them since they are not DPC-capable.
