Again, you are looking to your own foot. DVB_PLL is required for other
non-bt8xx cards.

You save RAM, at the risk of breaking DVB support and flooding the ML
with complains about broken stuff. No. It should also warn here also.

NO! You are looking only bttv boards.
If you take a look, DVB_PLL is required also by non-bttv frontends.

You proved by facts that dvb-bt8xx needs dst, dst_ca and dvb_pll.
Without those, several boards will stop working.
Your patch is broken, since it leaves several symbols undefined.

Again, please stop trying to offend people from the community. Next time
I'll stop answering such emails without advice.
