   4 Subject: [PATCH 31/42] thermal/drivers/mediatek/lvts: Fix parameter check in
   5  lvts_debugfs_init()
   6
   7 The documentation says "If an error occurs, ERR_PTR(-ERROR) will be
   8 returned" but the current code checks against a NULL pointer returned.
   9
  10 Fix this by checking if IS_ERR().
