- Subject: [PATCH 12/17] 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.
