[Qemu-devel] [PATCH 13/17] PCI: Convert pci_device_hot_add() to QObject |
Date: |
Tue, 17 Nov 2009 18:32:20 -0200 |
Return a QDict with information about the just added device.
This commit should not change user output.
Please, note that this patch does not do error handling
conversion. In error conditions the handler still calls
monitor_printf().
