[PATCH 0/6] em28xx: use common urb data copying function for vbi and non-vbi data streams

["Frank Schäfer" <fschaefer.oss@googlemail.com>]

Patches 1-5 prepare function em28xx_urb_data_copy_vbi() to also work with non-vbi video data.
Patch 6 finally renames em28xx_urb_data_copy_vbi() and changes to code to use this function for both, vbi and non-vbi video data streams.

The changes have been tested with the following devices:
- "SilverCrest 1.3 MPix webcam" (progressive, non-vbi)
- "Hauppauge HVR-900 (65008/A1C0)" (interlaced, vbi enabled and disabled)

This series applies on top of my previous patch series "em28xx: add support fur USB bulk transfers" V2.
