In the Linux kernel, the following vulnerability has been resolved:
clk: tegra: Fix refcount leak in tegra114_clock_init
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.

kernel: clk: tegra: Fix refcount leak in tegra114_clock_init
In the Linux kernel, the following vulnerability has been resolved:
clk: tegra: Fix refcount leak in tegra114_clock_init
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.
A reference count leak was found in the Linux kernel's Tegra114 clock driver. The tegra114_clock_init() function calls of_find_matching_node(), which returns a node pointer with an incremented reference count. The code fails to call of_node_put() when the node is no longer needed, resulting in a reference count leak that prevents proper resource cleanup.
