Suggestion:
If the patch adds value without breaking anything, include it.
Even if it's "ugly", you can easily clean it up later and "do it the
right way" (tm).
Providing you find time and cleaning it up is more important than
something useful.
I counted about 35 lines of actual logic in the patch, and I think
that's really about 20-25
if you ignore repetitions.
If there's a better way of coding it that someone (Markus? Michael?)
can think of in 5 minutes,
please let Uwe know, since I imagine he could fix it in about 5 minutes
with
his mind still fresh on the topic. Otherwise I suggest putting "clean
up" somewhere
low on the to-do list and moving on.
Regards,
Bill

In current kernel 2.6.22-rc3 the frontend module dvb-pll.c is attached as
a generic standard for all bt8xx-based DVB cards. This is no good
solution.
Fact is:
The only bt8xx-based card taking advantage of that pll library is the
DViCO FusionHDTV Lite 5. All other bt8xx-based DVB cards do not take any
advantage of this pll library.
The following patch corrects this problem without breaking any card
support. For further SOBs I do appreciate the relevant persons Cced.

NACK.
This hack is unacceptable. Uwe, Please have patience
In fact I had enough patience, for a couple of months now.
Even if you do not like it, it is a functionable compromise solution for now.
There is no technical reason to nack it at all. If there is one, then it's
either a personal issue or a matter of design.
The fact that you reacted so quickly prefares option 1 (i. e. personal issue).
And the tactical background of telling some other person to wait (or to be
patient) without offering an adequate time window for the WHEN is a gesture
of humiliation (I know that gesture already very well from Manu, and I do not
like it at all).
Above that you were not the only one I was asking for a SOB. I only wanted to
try fair play (i. e. not overstepping anybody).
Regards
Uwe
P. S.: To let somebody starve at the long arm: Ever heard what that means,
Mike? In fact I am not keen on flames, but I know people who provoke them by
their inacceptable gestures. And that's it what must become past in here.
The other people reading this I would appreciate to test the two patches and
complain if I have done anything wrong. My door stays open for real technical
criticism.
Thanks for reading :)
-- I have a few ideas
on how to do this without using #ifdef's , but I am spending my time on
other things right now. Trent also had some ideas on how remove the static
dependencies on dvb-pll, but we all have bigger fish to fry.
For the time being, you should use this on your own kernel configuration,
but this is not correct, and should not be pushed into mainline.

Mike Krufky
