[Qemu-commits] [COMMIT d29275f] Add exit callback to DeviceInfo.

Subject: [Qemu-commits] [COMMIT d29275f] Add exit callback to DeviceInfo.
Date: Mon, 05 Oct 2009 14:53:26 -0000

From: Gerd Hoffmann <address@hidden>

This adds a exit callback for device destruction to DeviceInfo, so
we can hook cleanups into qdev device destruction.

Followup patches will put that into use.
