[linux-dvb] Re: [PATCHES] Frontend kernel i2c conversion.

[Andreaz@t-online.de (Andreas Witte)]

Hi Kenneth !

Tried the latest cvs-grab and want to give you feedback for your work.
It seems something is damaged with the mt352 frontend.

Im also using the latest video4linux driver. I hope that the error isnt
rooted here. With a cvs-grab 2 days ago the mt352 was working perfect.

Below the feedback i got from dmesg while loading the mt352:

I've committed most of the changes today, what is left is DST, NXT6000 and
the
VES frontends. I've held those back, because they have some hary changes
that
need to be done, and since I found several bugs in the other changes before
committing there'll be more in these.

Please, people that have one of these frontends and are running Kernel 2.6.
CX24110, Grundig 29504 401/491, MT312/352

Update to latest CVS, make, run insmod.sh reload, and check if it's working,
then report back here on your result, so if there is bugs at least we'll
know
about them. Thanks.

Cheers,
Kenneth
