More precisely I call:
fe0->dvb.frontend = dvb_attach(s5h1411_attach,
&kworld_s5h1411_config,
&dev->i2c_adap);
Where kworld_s5h1411_config is:
static struct s5h1411_config kworld_s5h1411_config = {
.output_mode = S5H1411_SERIAL_OUTPUT,
.gpio = S5H1411_GPIO_ON,
.qam_if = S5H1411_IF_4000,
.vsb_if = S5H1411_IF_3250,
.inversion = S5H1411_INVERSION_ON,
.status_mode = S5H1411_DEMODLOCKING,
.mpeg_timing =
S5H1411_MPEGTIMING_CONTINOUS_NONINVERTING_CLOCK,
};
But fe0->dvb.frontend is null:
