The capabilities field traditionally contains the capabilities of the physical device, being a superset of all capabilities available at the several device nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means that there is a corresponding vbi node as well. And the capabilities field of both the video and vbi nodes should contain identical caps. However, it would be very useful to also have a capabilities field that contains just the caps for the currently open device, hence the new CAP bit and field.
