System: NetBSD s012 4.0 NetBSD 4.0 (NSW-S012) #11: Fri Mar 26 15:01:49 CET 2010

Architecture: x86_64
Machine: amd64
>Description:
        From 4.x to 5.0.2 in the iavc_softtc_t the send and recieve buffer
        elements changed type to "void*". So it is no longer possible to
        reference them - still done in iavc.c ...
>How-To-Repeat:
        Setup a kernel with the iavc driver and try to compile it.
>Fix:
        The following patch will remove the problem:
