Hi Mauro,
I was playing with a radio-only device yesterday when I noticed that it
somehow implemented G_STD. It turns out to be a side-effect of the G_STD
implementation in v4l2-ioctl.c:
case VIDIOC_G_STD:
{
v4l2_std_id *id = arg;
ret = 0;
/* Calls the specific handler */
if (ops->vidioc_g_std)
ret = ops->vidioc_g_std(file, fh, id);
else
*id = vfd->current_norm;
break;
}
I was thinking of fixing this by changing it as follows:
else if (vfd->tvnorms == 0)
return -EINVAL;
else
*id = vfd->current_norm;
Is this the correct solution? Or do you have a better idea?
Regards,
Hans
