media: mediatek: vcodec: Only free buffer VA that is not NULL

2024-07-11T10:50:58Z

[ Upstream commit eb005c801ec70ff4307727bd3bd6e8280169ef32 ] 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.

media: mediatek: vcodec: Fix oops when HEVC init fails

2024-03-26T08:52:58Z

The stateless HEVC decoder saves the instance pointer in the context regardless if the initialization worked or not. This caused a use after free, when the pointer is freed in case of a failure in the deinit function. Only store the instance pointer when the initialization was successful, to solve this issue.

media: mediatek: vcodec: Handle VP9 superframe bitstream with 8 sub-frames

2024-03-26T08:52:58Z

The VP9 bitstream uses superframes, which each contain 8 sub-frames, enable accessing the last superframe by increasing the range of the index vaidation as the maximum number of superframes is 8 and not 7, so that the last sub-frame can be decoded normally with the stateful VP9 decoder.
