The bug is still present in -rc6, but Michael Ellerman has a patch[0] 
which made the warning go away.

@Michael: will you post your patch with a Sign-Off, so that it can be 
          pushed into mainline?

Thanks,

The bug is still present in -rc6, but Michael Ellerman has a patch[0] 
which made the warning go away.

@Michael: will you post your patch with a Sign-Off, so that it can be 
          pushed into mainline?

Thanks,
Christian.

No, Benh and I decided it's better to just drop those properties all
together. But it's too late in this cycle for a patch like that just to
fix a warning - so we'll do that patch for 35.

Seems that

  r600 CS checker rejects narrow FBO renderbuffers
  https://bugs.freedesktop.org/show_bug.cgi?id=27609

never got added to the list.  It is still an issue as of 2.6.34-rc7.

At least the effects on b2c2-flexcop-pci are still valid, in linux-2.6
HEAD and linux-next (next-20100621).

I think we've crossed wires.  By second patch I mean the patch that
changes OF code.  That change has absolutely no bearing on the
flexcop-pci driver.  The patch to the flexcop-pci driver looks correct
to me, but it is completely unrelated to the OF badness.

Yes, the latter patch dodges the issue with flexcop driver by simply
skipping the directory creation, but both patches should be applied IMO.
The former to fix the flexcop driver because we can trivially fix it,
the latter to solve problems with any generic bogus firmware.

On brief review, they look like completely different issues.  I doubt
the second patch will fix the flexcop-pci issue.  I'll pick up the
device tree patch, but the flexcop-pci patch should go in by the
v4l/dvb tree.

So, now we have two patches for slightly different issues?

* http://lkml.indiana.edu/hypermail/linux/kernel/1006.0/00137.html
  ...fixes the flexcop-pci.c driver.

* http://patchwork.ozlabs.org/patch/52978/
  ...fixes "some bogus firmwares include properties with "/" in their

This is wasteful. :-)
Also, I hope we won't spit message every time allocation fail.

Cool, and we see:

./uni-n@f8000000/i2c@f8001000/i2c-bus@1/fan@5c/pulses_rev

Which is the one that needed fixing.

Maybe a little. It has to check every string to see if it contains a
"/". But then you save the cost of taking an exeception for the WARN,
which might make up the difference. But it's a one time fixup at boot,
so it's not going to be noticeable.

We do. Your system is mostly hosed anyway, but feel free to rate limit
it or something.

The error handling in there is a bit dubious, if the alloc fails we just
return the old name, which we know is bogus. It should probably return
NULL and the calling code can check - same for fixup_name().

Whatever, patches welcome :)

We do. Your system is mostly hosed anyway, but feel free to rate limit
it or something.

The error handling in there is a bit dubious, if the alloc fails we just
return the old name, which we know is bogus. It should probably return
NULL and the calling code can check - same for fixup_name().

I added GFP_KERNEL to kstrdup to make the compile error go away:

I have not done any performance tests, but I'd rather stick with the
