Subject: [PATCH v2 0/4] backlight: fix device-tree node lookups

A number of drivers have been using the wrong OF helper when doing child-node
lookups during probe. This meant that they were doing tree-wide searches rather
than matching on child nodes and that the parent node could end up being
prematurely freed.

v2
 - add patch 4/4 which fixes two node leaks in as3711_bl instead of marking
   the leaks using FIXMEs in patch 1/4
