[PATCH 0 of 6] Use usb_interface.dev for v4l2_device_register

[Janne Grunau]

Hi,

the documentation suggest and the current usb driver are using struct device
from the usb_device. As discussed for video_device parent the usb_interface
should be used. This has the advantage that v4l2_device_register creates
meaningfull names, for example "hdpvr usb2-3:1.0" instead of "usb 2-3".

This patch series updates Documentation/video4linux/v4l2-framework.txt and
hopefully all usb drivers uing v4l2_device.

The pvrusb2 and au0828 drivers are already overriding v4l2_device.name with a
driver name and a device counter. I removed that code since I suspect it was
only added to get meaningful names.
If the current names are preferred I'll update the patches.

regards,
Janne
