Re: dvb-s2 card "TeVii S472" (cx23885)

[Olli Salonen <olli.salonen@iki.fi>]

Hi Hendrik, Hans,

My media_tree Hendrik is pulling from Github is just a rather recent
copy of the media_tree master branch on git.linuxtv.org (it's missing
like the last 10 patches that have been added within the last 24
hours) with 2 simple patches on top that should not break anything.

Also, the media_build is recent, since you just cloned it.

Hans, do you know if there are any known issues with the current
media_build/media_tree on certain kernels?

Thanks.

Cheers,
-olli
