+Subject: [PATCH 13/15] pci: do not probe too early
+
+Probing is done before the PCIe bridge is fully activated and the
+address spaces does not get assigned to the PCIe devices. Without the
+address space the driver can not register to this device. With this
+patch the driver reregistration is done later.
