oops .. i think i have a small mistake in the patch. After the loop for
list_for_each_entry ends we are having:
if (iterator->base + iterator->ngpio <= chip->base)
goto found;

But at the end of the loop iterator will point to head. The condition in
the loop is &pos->member != (head).
I am sending v2 as reply to this thread. It will be great if you can
review and apply that instead of this one.
Sorry for the inconvenience. I guess christmas effect. :)
