Hmmm... Doesn't that expose a larger problem? The only place the ts2020_priv
struct is allocated is in ts2020_probe() within ts2020.c and the struct
definition is private to that file and so it can't be allocated from outside.
So if you don't pass through ts2020_probe(), fe->tuner_priv will remain NULL
and the driver will crash.
