I am seeing the same with m68k/allmodconfig and gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04). It is triggered by the second call to mxc_jpeg_get_plane_size() in mxc_jpeg_dec_irq(): if (q_data->fmt->mem_planes == 2) { payload = mxc_jpeg_get_plane_size(q_data, 1); vb2_set_plane_payload(&dst_buf->vb2_buf, 1, payload); } However, I am not seeing the issue with x86-64/allmodconfig and gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1). Bisected to commit ccc9f1db9c6b0620 ("media: imx-jpeg: Support contiguous and non contiguous format").
