From ddc4b58caf77f4b2ae2557082f910850c1c20d29 Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Thu, 10 Dec 2009 17:16:09 -0200 Subject: [PATCH] PCI: Convert pci_device_hot_add() to QObject 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().
