V4L/DVB (10135): v4l2: introduce v4l2_file_operations.
Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.
