libdvbpsi | branch: master | Daniel Kamil Kozar <dkk089 at gmail.com> | Sat Jul 18 21:49:53 2015 +0200| [b297e4d47c034f02de769f2011ef1791ba218031] | committer: Jean-Paul Saman

Fix bad operator precedence when reading handover_type in dr-4a generation

Due to the lack of parenthesis, the expression used to read handover_type was
read as (p_descriptor->p_data[7] & (0xF0 >> 4)).

(cherry picked from commit 61bb8944e881d602db9f77a89051ada310958b28)
