Subject: clk: ti: dra7-atl-clock: fix child-node lookups
From: Johan Hovold <johan@xxxxxxxxxx>
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.
Fixes: 9ac33b0ce81f ("CLK: TI: Driver for DRA7 ATL (Audio Tracking Logic)")
Fixes: 660e15519399 ("clk: ti: dra7-atl-clock: Fix of_node reference counting")
