Consolidate of_get_parent
This requires creating dummy of_node_{get,put} routines for sparc and sparc64. It also adds a read_lock around the parent accesses. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Paul Mackerras <paulus@samba.org> Acked-by: David S. Miller <davem@davemloft.net>
