[PATCH 02/19] [media] dvb-frontends/stv0910: cast the BER denominator shift exp to ULL

[Daniel Scheller <d.scheller.oss@gmail.com>]

From: Daniel Scheller <d.scheller@gmx.net>

To avoid miscalculations related to the BER denominator, the shift
expression needs to be casted as ULL.

Picked up from the upstream dddvb GIT.
