Subject: [PATCH v1] thermal/drivers/mediatek/lvts_thermal: fix error check in lvts_debugfs_init()
Date: Thu, 21 Sep 2023 17:10:50 +0800 [thread overview]
Message-ID: <20230921091057.3812-1-duminjie@vivo.com> (raw)
debugfs_create_dir() function returns an error value embedded in
the pointer (PTR_ERR). Evaluate the return value using IS_ERR
rather than checking for NULL.
