From 8a911107386b5c7a78a629f0fe29381cf0ea5f6f Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Thu, 17 Jun 2010 09:15:02 -0600 Subject: virtio-pci: fix bus master bug setting on load The comment suggests we're checking for the driver in the ready state and bus master disabled, but the code is checking that it's not in the ready state.
