Merge tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux
Pull virtio updates from Rusty Russell: "All trivial, thanks to the stuff which didn't quite make it time" * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: virtio_console: Initialize guest_connected=true for rproc_serial virtio: use module_virtio_driver. virtio: Add module driver macro for virtio drivers. virtio_console: Use virtio device index to generate port name virtio: make pci_device_id const virtio: make config_ops const virtio-mmio: fix wrong comment about register offset virtio_console: Let unconnected rproc device receive data.
