[linux-dvb] [Patch] Error in dvb_net.c on 64bit platforms

[Holger.Kiehl at dwd.de (Holger Kiehl)]

Hello

Removing several dvb net interfaces as follows:

        /sbin/ifconfig dvb0_4 down
        /sbin/ifconfig dvb0_3 down
        /sbin/ifconfig dvb0_2 down
        /sbin/ifconfig dvb0_1 down
        /sbin/ifconfig dvb0_0 down

Always produces an oops on a 64 bit system. On a 32 bit system this is no
problem. Applying the attached patch makes it work on 64 bit systems.
