[Qemu-devel] [PATCH 58/61] virtio-pci : cleanup : init, exit and reset functions.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

This remove the init, exit and reset functions as they are no longer used. The
new API virtio_pci_rst function is renamed virtio_pci_reset.
