clk: ti: dra7-atl-clock: fix child-node lookups
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") Cc: stable <stable@vger.kernel.org> # 3.16: 660e15519399 Cc: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Johan Hovold <johan@kernel.org> Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
