V4L/DVB (4972): Dvb-core: fix bug in CRC-32 checking on 64-bit systems
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.
