Subject: drivers/char/drm/ severely broken - with this it at least builds

Parts of drivers/char/drm/ is severely broken in 2.6.12-rc1-mm1 - this is
fair enough since it /is/ marked as broken. So, why am I writing this
mail? Well, I /tried/ to build some of the stuff in there, saw it blow up,
then tried to fix it, then gave up trying to fix it, got it into a state
where it's still completely broken and will blow up pretty bad if you try
to use it, but at least it now builds. I have absolutely no idea if any of
the changes I made will be useful to anyone, but I thought I'd at least
submit a patch with the changes I made, and if bits of it are useful, then
good, if not - ohh well..

See further below for some of the warnings and errors I initially got that
prompted my to try and fix it.

Here's a patch with the changes I made - very ugly, very broken, possibly
worse than it was, but perhaps there are some bits that are useful - you
never know. :

It is marked as broken because it is broken.. this won't fix it..

the only way the gamma driver could be fixed is if someone with a gamma
picks it up.. the number of people with those cards that might concievably
care is about 2 and so far they said they don't...

I'll probably drop it at some stage..but for now it is marked as broken
for a lot more reasons and your patch will not address any of them...

in fact it backs out some changes made to the drm that just were never
applied to gamma driver..

regards,
Dave.
