Revision 3fff0179e33cd7d0a688dab65700c46ad089e934 authored by Mark McLoughlin on 03 February 2009, 03:03:53 UTC, committed by Linus Torvalds on 03 February 2009, 03:17:56 UTC
The host really shouldn't be notifying us of config changes before the device status is VIRTIO_CONFIG_S_DRIVER or VIRTIO_CONFIG_S_DRIVER_OK. However, if we do happen to be interrupted while we're not attached to a driver, we really shouldn't oops. Prevent this simply by checking that device->driver is non-NULL before trying to notify the driver of config changes. Problem observed by doing a "set_link virtio.0 down" with QEMU before the net driver had been loaded.
