This is a note to let you know that I've just added the patch titled clk: tegra: Fix refcount leak in tegra210_clock_init to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-tegra-fix-refcount-leak-in-tegra210_clock_init.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ef6aacb4e3df38ca690e114836e85236901e7153 Author: Miaoqian Lin <linmq006@xxxxxxxxx> Date: Mon May 23 18:26:08 2022 +0400 clk: tegra: Fix refcount leak in tegra210_clock_init [ Upstream commit 56c78cb1f00a9dde8cd762131ce8f4c5eb046fbb ] of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
