add them.

matt mooney 3e4fda9f95 staging: usbip: change the busid size
Change busid size to correspond with SYSFS_BUS_ID_SIZE, which was
already being used in most cases. This eliminates the need to define
BUS_ID_SIZE in the userspace code.

Arnd Bergmann 9720b4bc76 staging/usbip: convert to kthread
usbip has its own infrastructure for managing kernel
threads, similar to kthread. By changing it to use
the standard functions, we can simplify the code
and get rid of one of the last BKL users at the
same time.

Includes changes suggested by Max Vozeler.

Max Vozeler 2d8f4595d1 staging: usbip: stub: update refcounts for devices and interfaces
The stub driver expects to access the usb interface
and usb device structures even if the device has been
disconnected in the meantime.

This change gets a reference to them in the stub probe
function using usb_get_intf()/usb_get_dev() and drops them
in the disconnect function.

This fixes an oops observed with a Logic Controls Line
display (0fa8:a030) which disconnects itself when it is
reset:

Endre Kollar aa5873e962 Staging: usbip: fix multiple interfaces
The stub_probe function instantiates an stub_dev object  for all
interfaces. Wich causes a problem.  The stub_dev object belongs to their
own interfaces. This patch creates the sdev object at the first
stub_probe call, the other calls associate the interfaces to this.
