I was in doubt and I almost backported that one too, but it seemed better
to not add it to just remove it at the end.
Btw, it seems that a latter patch on your tree removed it. The only difference
between the git tree and your tree at xc4000.c/xc4000.h is:
$ diff -uprBw drivers/media/common/tuners/xc4000.c /home/v4l/tmp/linux/drivers/media/common/tuners/xc4000.c

}

ret = xc_set_IF_frequency(priv, priv->if_khz);
So, maybe the above patch also needs to be added there.

If it doesn't, please try to apply the above patch.
Thanks,
Mauro
