From bc6b8275924b8af3d10ac35df0579d94fa169680 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sat, 13 Sep 2014 10:28:51 +0200 Subject: [PATCH] NFC: st21nfcb: remove error output In case we are not able to read out the NDLC/NCI header, we do not consider this as an issue and we will give a later chance. The NDLC layer will handle errors thanks to its internal timers.
