Subject: [PATCH 03/13] DVB: Allow frontend to set DELSYS/Modulation rather than querying fe->ops.info.type
With any tuner that can tune to multiple delivery systems/standards, it does
query fe->ops.info.type to determine frontend type and set the delivery
system type. fe->ops.info.type can handle only 4 delivery systems, viz FE_QPSK,
FE_QAM, FE_OFDM and FE_ATSC.
The change allows the tuner to be set to any delivery system specified in
fe_delivery_system_t and any modulation as specified in fe_modulation_t,
thereby simplification of issues.
