[Qemu-devel] [PATCH 10/18] qom: release previous object when setting

[minyard]

From: Corey Minyard <address@hidden>

When setting an object, if you don't release the previous object
that was there, it may become unusable.  This change allows a
chardev to be removed from one object's properties and added to
another's.
