Hmm, I am actually doing this in a frontend driver I'm currently developing, in the get_frontend() callback function: if (fe->ops.tuner_ops.get_bandwidth) { ret = fe->ops.tuner_ops.get_bandwidth(fe, &bandwidth); if (ret) goto err; props->bandwidth_hz = bandwidth; } The documentation for get_frontend() states that it should return the parameters actually in use. And these might differ from the requested ones. So I see some value in filling in the actually applied bandwidth filter there. > OK! I'll wait for your patch. Posted.
