From e5d23a8cc38c555f9f3a40dcc5d14030105df9a8 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Fri, 16 May 2014 11:41:57 +0930 Subject: virtio-rng: fix boot with virtio-rng device Commit "virtio-rng: support multiple virtio-rng devices" has broken boot with a virtio-rng device because the 'init' callback of the virtio-rng device was left unitialized to garbage, and got called by the hwrng infrastructure, killing the guest on boot.
