Subject: isa: QOM'ify isa_bus_from_device()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3e7b8f4e6f507e09e27b7449f3744596f19c0083;p=qemu.git

isa: QOM'ify isa_bus_from_device()

DeviceState::parent_bus is document as private and should be accessed
through qdev_get_parent_bus(). Use a DEVICE() cast instead of accessing
ISADevice's qdev field directly. Use ISA_BUS() in place of DO_UPCAST().
