Adds an equivalent of usbip_host_driver for the vudc. Most of the code is already shared, but this adds some vudc specific code for getting information about devices. Based on code created in cooperation with Open Operating Systems Student Society at University of Warsaw (O2S3@UW) consisting of: Igor Kotrasinski <ikotrasinsk@gmail.com> Karol Kosik <karo9@interia.eu> Ewelina Kosmider <3w3lfin@gmail.com> Dawid Lazarczyk <lazarczyk.dawid@gmail.com> Piotr Szulc <ps347277@students.mimuw.edu.pl> Tutor and project owner: Krzysztof Opasiak <k.opasiak@samsung.com> Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
