[Qemu-devel] [PATCH] Print error when failing to load PCI config data |

From: "Dr. David Alan Gilbert" <address@hidden>
When loading migration fails due to a disagreement about
PCI config data we don't currently get any errors explaining
that was the cause of the problem or which byte in the config
data was at fault.
