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

[Jan Kiszka]

From: Jan Kiszka <jan.kis...@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.

This is also one piece in the puzzle of getting CPU hot-plug work.
