The good news is that it doesn't matter now as Andrew fixed Conke's patches
manually and applied them to -mm [ but without my Acked-by-s :( ].

I applied three pathces, but there's been such a storm of inadequately
changelogged mangled patches that I have little confidence that what I
applied was complete and up-to-date.

> [ but without my Acked-by-s :( ].

oop.

Here are the three patches. Conke, can you please tell us whether this is
all correct and complete?


From: "Conke Hu" <[email protected]>

A previous patch to atiixp.c was removed but some code has not been
cleaned. Now we remove these code sine they are no use any longer.
