Yes, this thing

	do {
		remote_miu = sock->remote_miu > LLCP_MAX_MIU ?
				local->remote_miu : sock->remote_miu;

		frag_len = min_t(size_t, remote_miu, remaining_len);

		pr_debug("Fragment %zd bytes remaining %zd",
			 frag_len, remaining_len);

		pdu = nfc_alloc_send_skb(sock->dev, &sock->sk, MSG_DONTWAIT,
					 frag_len + LLCP_HEADER_SIZE, &err);
		if (pdu == NULL) {
			pr_err("Could not allocate PDU\n");
			continue;
			^^^^^^^^
		}

is basically

	do {
		pr_err("Could not allocate PDU\n");
	} while (1)

Can cause problems sometimes. But this loop is a bit worrisome
even without the printk() call.

>From printk() side, we only can do rate limiting here. Would be
great if nfc maintainers could take a look and tweak the loop
maybe.

And of course I ended up patching the wrong function...
What I actually meant was:
