[Qemu-devel] [PATCH v2] qdev: Reset hot-plugged devices

[Jan Kiszka <jan.kiszka@web.de>]

From: Jan Kiszka <jan.kiszka@siemens.com>

Device models rely on the core invoking their reset handlers after init.
We do this in the cold-plug case, but so far we miss this step after
hot-plug.

Changes in v2:
 - move reset to qdev_init in case the device is created by the
   hot-plugged one (composed devices)
