From 72030a2eeb182575f1bf2383f1e9267d4a6ece61 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Mon, 11 Aug 2014 00:04:52 +0200 Subject: [PATCH] NFC: st21nfca: Change nfcid3 generation nfcid3 is based on sensf_res value. target->sensf is never NULL as it is a table. Check the sensf_res_len instead to make sure sensf_res is set or not.
