In the Linux kernel, the following vulnerability has been resolved:

drm/rockchip: analogix_dp: Fix OF node reference leak via auto cleanup

Sashiko reported a reference leak in rockchip_dp_drm_encoder_enable(), the of_get_child_by_name() function does not call of_node_put() in a symmetrical way [1].

Fix the device node reference leak by using __free(device_node) to automatically manage of_node_put() for all device nodes.
