4 | Subject: clk: ti: dra7-atl-clock: fix child-node lookups | |
5 | ||

8 | commit 33ec6dbc5a02677509d97fe36cd2105753f0f0ea upstream. | |
9 | ||
10 | Fix child node-lookup during probe, which ended up searching the whole | |
11 | device tree depth-first starting at parent rather than just matching on | |
12 | its children. | |
13 | ||
14 | Note that the original premature free of the parent node has already | |
15 | been fixed separately, but that fix was apparently never backported to | |
16 | stable. | |
17 | ||
18 | Fixes: 9ac33b0ce81f ("CLK: TI: Driver for DRA7 ATL (Audio Tracking Logic)") | |
19 | Fixes: 660e15519399 ("clk: ti: dra7-atl-clock: Fix of_node reference counting") | |
