parisc: remove klist iterators
commit 11c3b5c3e08f4d855cbef52883c266b9ab9df879
Author: Greg Kroah-Hartman <gregkh@suse.de>
Date: Tue Dec 16 12:24:56 2008 -0800
driver core: move klist_children into private structure
Broke our parisc build pretty badly because we touch the klists directly
in three cases (AGP, SBA and GSC). Although GregKH will revert this
patch, there's no reason we should be using the iterators directly, we
can just move to the standard device_for_each_child() API.
