[PATCH 10/28] V4L/DVB (4972): Dvb-core: fix bug in CRC-32 checkingon 64-bit systems

From: Mauro Carvalho Chehab
Date: Wed Dec 27 2006 - 12:18:55 EST

From: Ang Way Chuang <wcang@xxxxxxxxxxxxx>

CRC-32 checking during ULE decapsulation always failed on x86_64 systems due
to the size of a variable used to store CRC. This bug was discovered on
Fedora Core 6 with kernel-2.6.18-1.2849. The i386 counterpart has no such
problem. This patch has been tested on 64-bit system as well as 32-bit system.
