The values 0-4 indicates the signal has been locked, provided that current_std != STD_INVALID. > Signed-off-by: Roel Kluin <[email protected]> > --- > diff --git a/drivers/media/video/tvp514x.c > b/drivers/media/video/tvp514x.c > index 8e23aa5..5f4cbc2 100644 > --- a/drivers/media/video/tvp514x.c > +++ b/drivers/media/video/tvp514x.c > @@ -686,7 +686,7 @@ static int ioctl_s_routing(struct > v4l2_int_device *s, > break; /* Input detected */ > } > > - if ((current_std == STD_INVALID) || (try_count < 0)) > + if ((current_std == STD_INVALID) || (try_count <= 0)) > return -EINVAL; > > decoder->current_std = current_std; [Hiremath, Vaibhav] I believe we don't need this fix here. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
