[Qemu-devel] [PULL 1/1] mtp: linux guest detection fix.

[Gerd Hoffmann <kraxel@redhat.com>]

Attach a name to the MTP interface (android phones have this too).

With this patch recent linux guests such as fedora 20 happily detect and
use the device.  It shows up in nautilus file manager automatically, and
simple-mtpfs can mount it.
