[Qemu-arm] [RFC v2 5/6] pci: Set phb->bus inside pci_host_bus_init_inplace() |
|
Date: |
Tue, 18 Apr 2017 19:17:23 -0300 |
Every single caller of pci_host_bus_init*() sets phb->bus to point to
'bus'. Do that inside pci_bus_new_inplace() to avoid code duplication
and make it harder to break.
Generated using the following Coccinelle patch:

expression phb;
expression list ARGS;
