[Qemu-devel] [PATCH 17/56] qemu-char: Fix ID reuse after chardev-remove


From: Michael Roth
Subject: [Qemu-devel] [PATCH 17/56] qemu-char: Fix ID reuse after chardev-remove for qapi-based init
Date: Tue, 13 Aug 2013 10:10:41 -0500

From: Markus Armbruster <address@hidden>

Commit 2c5f488 introduced qapi-based character device initialization
as a new code path in qemu_chr_new_from_opts().  Unfortunately, it
failed to store parameter opts in the new chardev.  Therefore,
qemu_chr_delete() doesn't delete it.  Even though the device is gone,
its options linger, and any attempt to create another one with the
same ID fails.
