Just to reiterate to all users, this changeset corrects the rf input switching
problems on both the KWorld ATSC110 and the ATi HDTV Wonder.


Please pull from:



- [PATCH] nxt200x: fix rf input switching

...to fix the TUV1236d code, bringing it up to speed with the kernel.  ...I
imported that changeset directly from hg on kernel.org, so I forgot to add the
'kernel-sync' tag before pushing it up.  (otherwise, I would have asked for the
pull earlier) ...  but given the demand, and the fact that I'll be away from my
dev box for the next few days, I wont be able to re-push it till I get back.

Please just make note of the fact that "[PATCH] nxt200x: fix rf input switching
" is a kernel-sync patch, that Linus already has it in his tree.

As for 2.6.22 ...  I have an alternate idea that I sent to Trent in private for
his review...  He expressed some ideas on ways to improve my patch.  Trent and I
are going to discuss this a bit before I post the new patch to the mailing list.

After that is all done, pending approval by the other dvb developers, then I'll
send it on to you.

Also, please note:  m1k.net is down, and it might be permanent.  Please refrain
from using my @m1k.net email address (at least, for now), as it's unlikely that
I'll ever receive that mail.
