[media] m88ds3103: possible uninitialized scalar variable
It was possible that tuner_frequency variable, used for carrier offset
compensation, was uninitialized. That happens when tuner
.get_frequency() callback is not defined.
Currently that case is not possible as only used tuner has this callback.
Coverity CID 1166057: Uninitialized scalar variable (UNINIT)
