From bf93b23582af410df8e9ddd682e9a5c4d48b2c65 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Sat, 11 Nov 2017 17:29:29 +0100 Subject: [PATCH] clk: ti: dra7-atl-clock: fix child-node lookups commit 33ec6dbc5a02677509d97fe36cd2105753f0f0ea upstream. Fix child node-lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children. Note that the original premature free of the parent node has already been fixed separately, but that fix was apparently never backported to stable.
