From fec44a8c70e23f0f8433a28e824ce6dae4de8cde Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 16 Mar 2016 17:06:02 +0000 Subject: [PATCH] sd: Fix "info qtree" on boards with SD cards The SD card object is not a SysBusDevice, so don't create it with qdev_create() if we're not assigning it to a specific bus; use object_new() instead. This was causing 'info qtree' to segfault on boards with SD cards, because qdev_create(NULL, TYPE_FOO) puts the created object on the system bus, and then we may try to run functions like sysbus_dev_print() on it, which fail when casting the object to SysBusDevice. (This is the same mistake that we made with the NAND device and fixed in commit 6749695eaaf346c1.)
