   4 Subject: [PATCH 12/17] pci: do not probe too early
   5
   6 Probing is done before the PCIe bridge is fully activated and the
   7 address spaces does not get assigned to the PCIe devices. Without the
   8 address space the driver can not register to this device. With this
   9 patch the driver reregistration is done later.
