pixfmt->height) / BITS_PER_BYTE; No need for parentheses, and I'd wrap the line. Or replace BITS_PER_BYTE with 8: pixfmt->sizeimage = pixfmt->width * pixfmt->height * cc->bpp / 8; which I think is as readable. You also need to handle bytesperline. I'd go one step further, and get rid of imx7_csi_mbus_fmt_to_pix_fmt(). This is historical, there's no need to convert between mbus and pixel formats anymore. > + pixfmt->field = V4L2_FIELD_NONE; This should probably be moved to a separate patch. Interlaced format handling is broken, there's no IDMAC on i.MX7. The code comes from shared helpers with i.MX6 before the driver got destaged. > + > if (compose) { > compose->width = fmt_src.width; > compose->height = fmt_src.height; -- Regards, Laurent Pinchart _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
