From 19ad9f29751ca385262c63f513f75610962c40a0 Mon Sep 17 00:00:00 2001 From: Minjie Du Date: Thu, 13 Jul 2023 12:24:12 +0800 Subject: [PATCH] thermal/drivers/mediatek/lvts: Fix parameter check in lvts_debugfs_init() The documentation says "If an error occurs, ERR_PTR(-ERROR) will be returned" but the current code checks against a NULL pointer returned. Fix this by checking if IS_ERR().
