<snip>
Here are the three patches. Conke, can you please tell us whether this is
all correct and complete?
From: "Conke Hu" <conke.hu@xxxxxxxxx>
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.

This patch fixes the bug.
