[PATCH]: gspca: use usb interface as parent

[Hans de Goede]

Hi all,

As discussed in the:
"v4l parent for usb device interface or device?"
thread, here is a patch for gspca to make it use
the usb interface as its parent device, instead
of the usb device.

Regards,

Hans

p.s.

I'll also push a patch to my libv4l repo, with
matching libv4l changes so that libv4l's upside
down cam detections stays working with this change.

Note: this libv4l patch also fixes libv4l upside
down detection for the new device numbering style.
