[Qemu-devel] [PATCH 7/8] pci: eliminate work around in pci_device_reset().

[Isaku Yamahata]

Eliminate work around in pci_device_reset() by
making each pci reset function to call pci_device_reset_default().
Each device should know reset itself. It shouldn't be done pci generic
layer automatically. PCI layer should just signal reset and let each device
respond to reset.
