I really don't care for this j++ which is tucked inside a condition.

	int fmt_idx = -1;
	unsigned int i;

	for (i = 0, i < desc->num_decoded_fmts; i++) {
		if (!rkvdec_image_fmt_match(desc->decoded_fmts[i].image_fmt,
					    image_fmt))
			continue;
		fmt_idx++;
		if (index == fmt_idx)
			return desc->decoded_fmts[i].fourcc;
	}

	return 0;

Don't resend if this is the only issue, but if you do resend could you
get rid of the j++?
