+Subject: [PATCH 201/203] PCI: mvebu: increment nports only for registered
+ ports
+
+The number of ports is probed by counting the number of available child nodes.
+Later on, the registration of a port can fail and cause a mismatch between
+the ->nports counter and registered ports. This patch modifies the counting
+strategy, to make ->nports represent the number of registered ports instead
+of the number of available childs.
