From f1abed171fa565448d229afb814f66ab6d104d44 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 26 Jun 2013 17:53:09 +0200 Subject: [PATCH] NFC: pn533: Fix hardware busy loop when establishing the LLCP link By using the standard setting for the regular pn533 dongles, we no longer wait for ever for an ATR_RES. Without this, a failing ATR_REQ will put the hardware into a busy loop, constantly waiting for an ATR_RES.
