Subject: [PATCH] MAD16 module
Date: Wed, 11 Aug 1999 15:53:20 +0000 [thread overview]
Message-ID: <marc-linux-sound-93439969129444@msgid-missing> (raw)
[-- Attachment #1: Type: text/plain, Size: 204 bytes --]
Patch to correct the problem I mentioned before.
Now the cdrom controller gets properly initialized and
for the people not using the cdrom controller (like me)
things don't get messed up.
