[PATCH 3.14 31/79] virtio_console: init work unconditionally

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Michael S. Tsirkin" <mst@xxxxxxxxxx>

commit 4f6e24ed9de8634d6471ef86b382cba6d4e57ca8 upstream.

when multiport is off, we don't initialize config work,
but we then cancel uninitialized control_work on freeze.
