Browse files Browse the repository at this point in the history 
This patch synchronizes current bttv support on V4L with linux kernel and
adds support to Adlink RTV24 card.

It is asked that *every* patch to V4L stuff to be first submitted to
video4linux-list@redhat.com.

From: "J.A. Magallon" <jamagallon@able.es>
