The implementation in the source code is ambiguous. The warning means that
either no tuner was detected or that multiple were detected (at most four
from 0x60 to 0x63), but the driver didn't pass its check when trying to
choose either one automatically, and then it uses a default address, 0x60.
Nevertheless, in a later check the driver thinks the tuner at the chosen
address works or else it would report an error "tuner access failed".
