Subject: [PATCH] backlight: sky81452-backlight: replace of_node_put with __free
Date: Wed, 1 May 2024 18:21:46 +0530 [thread overview]
Message-ID: <20240501125146.33648-1-prosunofficial@gmail.com> (raw)
Use the new cleanup magic to replace of_node_put() with
__free(device_node) marking to auto release when they get out of scope.
