Unfortunately, it turned out that the devres\nrelease doesn't work for this case; namely, since the codec resource\nrelease happens before the devm call chain, it triggers a NULL\ndereference or a UAF for a stale set_brightness_delay callback.\n\nFor fixing the bug, this patch changes the LED class device register\nand unregister in a manual manner without devres, keeping the\ninstances in hda_gen_spec."
