Subject: [PATCH 2/2] MIPS: implement pcibios_get_phb_of_node
|
|
|
|
The of_node field of the device assigned to a
|
|
PCI bus is used during scanning of the PCI bus.
|
|
However on MIPS, the of_node field is assigned
|
|
only after the bus has been scanned.
|
|
|
|
Implement the architecture specific version of
|
|
'pcibios_get_phb_of_node'. Which ensures that the
|
|
PCI driver core will initialize the of_node field
|
|
before starting the scan.
|
|
|
|
Also remove the local assignment of bus->dev.of_node,
|
|
it is not needed after the patch.
