[PATCH] Fix ConnectorTable crash in radeon_output.c

[Hans Verkuil]

Hi Alex,

A few weeks ago I spent some time trying to get my sam440ep PPC board to
work with a recent kernel/debian distro. I discovered a bug causing it
to crash. It's a regression of commit 82f12e5a40c1fbcb91910a0f8b725c34fff02aae
from January 2009. Clearly, this board isn't used very often :-)

It would be nice if this patch is merged.

I've also tried to get drm to work with this board, but unfortunately the colors
have the wrong endianness and I don't really have any idea how to fix that (or
even where to look for that matter). For the record, this board has a ATI Radeon
Mobility M9.

Regards,

	Hans

Patch description:

The sam440ep PPC board requires a ConnectorTable xorg.conf option, but putting
in that option causes the radeon driver to crash. I finally traced it to a
copy-and-paste bug in radeon_output.c as a result of a major rework in commit
82f12e5a40c1fbcb91910a0f8b725c34fff02aae.

The actual crash occurred in RADEONPrintPortMap().
