Yes, the driver is weird, as it encapsulates the demod code
inside it , instead of using the saa7115 driver, that covers most
of saa711x devices, including saa7113.

Btw, is this driver really needed? The em28xx driver has support
for the Easy Cap Capture DC-60 model (I had access to one of those
in the past, and I know that the driver works properly).

What's the chipset using on your Easycap device?

If it is not an Empiatech em28xx USB bridge, then it makes sense
to have a separate driver for it. Otherwise, it is just easier
and better to add support for your device there.
