Subject: virtio-serial: Don't clear ->have_data() pointer after unplug
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fee063c07f20b442ef4bedef834ab0a3bf55b562;p=qemu.git

virtio-serial: Don't clear ->have_data() pointer after unplug

After a port unplug operation, the port->info->have_data() pointer was
set to NULL.  The problem is, the ->info struct is shared by all ports,
effectively disabling writes to other ports.
