Hi Antti,

I'm assuming that you're reviewing this patchset, so, I'll update patchwork status
accordingly.

Moikka Mauro et all,

I will NACK this.

Surely it is not proper solution. And after all, I haven't got any other 
reports there is such problem. AF9015 is probably most common DVB-T USB 
hardware today and if there is major problems I am the first person got 
reports.

regards,
Antti

If you are interested, I'm willing to do more testing on this particular 
device, to clear up ;)
