+ *    sound/pnp.c - Temporary kludge for PnP soundcards.
+ *
+ *      Copyright by Hannu Savolainen 1997.
+ *
+ *      This file is just a temporary solution to be used with
+ *      PnP soundcards until final kernel PnP support gets ready.
+ *      The code contained in this file is largely untested and
+ *      may cause failures in some systems. In particular it will
+ *      cause troubles with other PnP ISA cards such as network cards.
+ *      This file is also incompatible with (future) PnP support in kernel.
+ *
+ *      For the above reasons I don't want this file to be widely distributed.
+ *      You have permission to use this file with this particular sound driver
+ *      and only for your own evaluation purposes. Any other use of this file
+ *      or parts of it requires written permission by the author.
