From 51c6d61ac58844b5e3e0d28271084c06f6a15371 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Sun, 14 Aug 2011 17:52:31 +0300 Subject: virtio-console: Use virtio_config_val() for retrieving config This patch modifies virtio-console to use virtio_config_val() instead of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve optional values from the config space.
