the patch below contains several cleanups for drivers/media/video/, most
of them are:
- needlessly global code made static
- currenly unused code removed
Please comment on this, especially if patches for in-kernel users of
currently unused code are pending.

No, not this way in one big blob please. It would be very nice if you
can split that into smaller pieces:
(1) The ObviouslyCorrect stuff, i.e. make stuff static which isn't
declared in any header file.
(2) The stuff which needs some more careful review (drop functions,
drop stuff from header files, ...).
Especially the later please splitted by driver, so the driver
maintainers can have a look (which is kida problematic for some v4l
drivers as there is no active maintainer currently, but I'd prefeare
to have that separately in my inbox neverless).
I don't like your attitude to just drop stuff as "cleanup". If
functions are declared in a header file they are usually for a reason,
thus that kind of stuff needs some careful checking whenever these
reasons still exist or not. Not every function which isn't used at the
moment automatically is useless. cx88_risc_disasm() for example is
useful for debugging the driver. And that there is no in-kernel user
for exported functions doesn't mean that nobody uses it. The stuff
exported by bttv-if is used by lirc for example.

OK, the patches follow as followups to this mail.

That's why I prefixed the subject with "RFC"...

But couldn't this be #if 0'ed?
This way it was easily available for developers, but wouldn't use space
for all users.

I've removed the bttv-if changes from the patches.
BTW: Can't lirc be included in the main kernel?

of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.

This patch only makes code that is neither mentioned in a header file
nor declared extern in another file static.
Additionally, it does remove the unused function stradis_driver from
stradis.c (or what should the comment mean?).

Thanks, I'll look through that when preparing my next patch set.
Will take some time through as I've just pushed updates and also
will be offline for a week soon.

Yes, it could.

I don't care, the lirc people should, I already have to many projects
for my time.
Last time I checked the code was in a pretty bad state, it needs a
major overhaul IMHO before it can be included. Lots of historical
cruft (dates back to 2.2 days), parts are not SMP save, ...
At least for the TV cards I prefeare to use the linux input layer
instead, see the ir-kbd-* drivers. They didn't catch up yet with
lirc on supported hardware through, so I don't want break lirc now.
But the stuff in bttv-if.c is obsolete and I plan to drop that
altogether some day, see the comment about that in bttv.h. Given that
there will be no 2.7 in near future due to the new devel model I maybe
should make that a time bomb instead ...
