Added check if pointer is null and removed indentation for common path Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: sundar <prosunofficial@gmail.com> --- Fixed nitpicks in code according to comments received on other patch. https://lore.kernel.org/all/2024041103-doornail-professor-7c1e@gregkh/ goal is to get rid of of_node_put,but sending this patch first to do one thing at a time.
