From 0531107e1cdc4f5254116c1bf972c62fb024a466 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Tue, 20 May 2014 22:21:56 +0200 Subject: NFC: st21nfca: Improve read length sequence for P2P mode. A DEP_RES with a SUPERVISOR PDU can be up to 16 bytes long. In order to avoid useless read during p2p, extend first read sequence to 16 and reduce third sequence to 12 to keep same total on the full sequence.
