For memory alloc operation: the v4l2 framework malloc a memory, the base addr is vb2_buffer and the size is sizeof(struct mtk_jpeg_src_buf), mtk_jpeg_src_buf could get itself addr by container_of like that: vb2_buffer -> vb2_v4l2_buffer -> mtk_jpeg_src_buf. vb2_v4l2_buffer must keep on the top of mtk_jpeg_src_buf.
