hot-swapping of such controllers. If a controllers is removed then all
the controllers stop working and cpu usage gets high. The attached patch
(against 2.6.11-rc3) corrects this bug by checking the information read
from the controller. If the message length is bigger than the maximum
possible, then it means the controller is not there and therefore this
value should be discarded.

Note that this is a re-send of a previous patch now that the patch of
Peter (which had to be applied before this one) has been intregrated in
the vanilla kernel. It's Peter's version modified to apply cleanly
against 2.6.11-rc3 plus a fix in the comment.
