| Subject: clk: ti: dra7-atl-clock: fix child-node lookups |
| |
| From: Johan Hovold <johan@kernel.org> |
| |
| 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") |
