From eb005c801ec70ff4307727bd3bd6e8280169ef32 Mon Sep 17 00:00:00 2001 From: Fei Shao Date: Thu, 21 Dec 2023 09:17:46 +0000 Subject: [PATCH] media: mediatek: vcodec: Only free buffer VA that is not NULL In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly called only when the buffer to free exists, there are some instances that didn't do the check and triggered warnings in practice. We believe those checks were forgotten unintentionally. Add the checks back to fix the warnings.
