[PATCH 0/4] virtio: validate device-reported values across drivers

These four patches harden virtio-mem, virtio_input, and virtio_console 
against untrusted values coming from the device/backend side of the virtio
interface. The fourth fixes a use-after-free in virtio_console caused by a
missing refcount.

Hari Mishal (4):
  virtio-mem: validate device-reported block size
  virtio_input: validate device-reported multitouch slot count
  virtio_console: avoid NULL portdev dereference in in_intr()
  virtio_console: take a kref in find_port_by_vq() to fix port UAF
