This patch series refactors the frame data processing code in em28xx-video.c to
- reduce code duplication
- fix a bug in vbi data processing
- prepare for adding em25xx/em276x frame data processing support
- clean up the code and make it easier to understand
It applies on top of my previous patch series
"em28xx: add support fur USB bulk transfers"
"em28xx: use common urb data copying function for vbi and non-vbi 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)

em28xx: em28xx_urb_data_copy(): move duplicate code for
capture_type=0 and capture_type=2 to a function
em28xx: move the em2710/em2750/em28xx specific frame data processing
code to a separate function
