[Qemu-devel] [PATCH v2 2/2] virtio-console: no need to remove char handlers explicitly

[Amit Shah <amit.shah@redhat.com>]

qdev is now equipped (thanks to the last commit) to disassociate
chardevs from the qdev devices on the devices going away.  So doing it
in the virtio-console driver is not necessary.

Since that was the only thing being done in the qdev exit method, drop
it entirely.
