I'm guessing that was this?

static unsigned int kyber_sched_tags_shift(struct kyber_queue_data *kqd)
{
	/*
	 * All of the hardware queues have the same depth, so we can just grab
	 * the shift of the first one.
	 */
	return kqd->q->queue_hw_ctx[0]->sched_tags->bitmap_tags.sb.shift;
}

If not, that'll need to be fixed up.
