From fa00e8fed457841cb24219dbe3cfba7d56de6317 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Tue, 3 Feb 2015 19:48:08 +0100 Subject: [PATCH] NFC: nci: Move NFCEE discovery logic NFCEE_DISCOVER_CMD is a specified NCI command used to discover NFCEE IDs. Move nci_nfcee_discover() call to nci_discover_se() in order to guarantee: - NFCEE_DISCOVER_CMD run when the NCI state machine is initialized - NFCEE_DISCOVER_CMD is not run in case there is not discover_se hook defined by a NFC device driver.
