## Overview

In the Linux kernel, the following vulnerability has been resolved:

drm/mediatek: Add missing IS_ERR check for ovl_adaptor platform device

platform_device_register_data() can fail and return an ERR_PTR, but the
return value is used without checking, leading to an invalid pointer
being stored in ddp_comp[].dev and passed to component_match_add() and
mtk_ddp_comp_init(), which could result in a kernel crash.

Add an IS_ERR() check to jump to the error handling path on failure.
