Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: mediatek: vcodec: Only free buffer VA that is not NULL<br /> <br /> In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly<br /> called only when the buffer to free exists, there are some instances<br /> that didn&amp;#39;t do the check and triggered warnings in practice.<br /> <br /> We believe those checks were forgotten unintentionally. Add the checks<br /> back to fix the warnings.
