I would appreciate if somebody would removes the driver from the linux 
kernel. I suggested that some years ago 2014-06-23 (just scroll down):
https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201406

You should also find that thread in the kernel-janitors@vger.kernel.org 
and linux-media@vger.kernel.org Mailinglist archive.

I know of one person that is still using this old type of card's but he 
uses a 2.6.x Kernel on a old machine, using old software releases.
https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201709

That type of card were introduced about ~20 years ago. I think it is a 
good moment to say goodbye to that type of cards.

auf hoffentlich bald,

Berni the Chaos of Woodquarter
