modify jpegenc device run func interface and add worker for encode
The description makes less sense.
quoted hunk
+static void mtk_jpegenc_worker(struct work_struct *work) { - struct mtk_jpeg_ctx *ctx = priv; + struct mtk_jpeg_ctx *ctx = container_of(work, struct mtk_jpeg_ctx, + jpeg_work); struct mtk_jpeg_dev *jpeg = ctx->jpeg; + struct mtk_jpeg_dev *comp_jpeg[MTK_JPEGENC_HW_MAX]; struct vb2_v4l2_buffer *src_buf, *dst_buf; enum vb2_buffer_state buf_state = VB2_BUF_STATE_ERROR; unsigned long flags; - int ret; + struct mtk_jpeg_src_buf *jpeg_src_buf, *jpeg_dst_buf; + int ret, i, hw_id = 0;
hw_id doesn't need to be initialized.

Hard-coded refers to hw_rdy[0] and hw_rdy[1] here?

Why it uses reg_base[0]?
