eyetoy: frame size off by some bytes

Off by sizeof(header1) + sizeof(header2)?

[Florin9doi]

The total size (header1+2+mpeg_frame_data) is never calculated or used and mpeg_frame_offset is used to iterate in mpeg_frame_data, not in header1+2+mpeg_frame_data. I can't find any issue. Maybe to verify that data_pk isn't larger than mpeg_frame_size at first step, but is unlikely.
