I'm using the latest tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-2.6.git
Is that OK?

Yes, the array in the struct has 12 entries, but the comments in the
af9015 code said: "/* max 9 */". So I stuck to the comment.
I would make use of the entries left. The af9015_properties is an array
with currently 3 entries. Each entries currently all have 9 device
description. Do you prefer that I add the new description:
- in the first entry,
- just below the existing A850, (my pick)
- or in the last entry?
And to answer your previous question:

Yes, I just tried without the hack and it breaks. With the hack, it works.
I can provide the failing dmesg output if needed (see working one below).

OK, got it. I'm afraid the A850T is just a A850 re-branded for the french
market. Here is the relevant dmesg output when I plug the stick (with my
changes applied on a 2.6.35.6):

See the part that reads:
input: AVerMedia A850 DVBT as /class/input/input14
^^^^^^^^^^^^^^^^^^^
This is no kernel message, and (I guess) it comes as the ID string from the
device. It also appears on a machine where I have no DVB support.
So I believe the patch is OK in the state, unless you really want a new
device description, instead of adding to the existing A850 ( yes, granted,
it's not the same color ;-] ). What is your final word? ;-)
Anyway, before you get action and push this patch, Eric helped in the testing
so far. Maybe he'll want to add his tested-by?
Thank you very much for your comments and guidance!
Regards,
Yann E. MORIN.
