From: kernel test robot <lkp@intel.com>
drivers/gpu/drm/bridge/ite-it66121.c:944:5-11: inconsistent IS_ERR and PTR_ERR on line 946.
PTR_ERR should access the value just tested by IS_ERR
Semantic patch information:
There can be false positives in the patch case, where it is the call to
IS_ERR that is wrong.
