   4 Subject: clk: ti: dra7-atl-clock: fix child-node lookups
   5
   6 From: Johan Hovold <johan@kernel.org>
   7
   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.

  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")
