[PATCH v1] thermal/drivers/mediatek/lvts_thermal: fix error check in lvts_debugfs_init()

From: Minjie Du
Date: Thu Sep 21 2023 - 13:00:34 EST


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.
