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.
