From 0b456c418a5595b9d67f300c9ac6a2441e774603 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Tue, 7 May 2013 19:22:11 +0200 Subject: NFC: Remove the static supported_se field Supported secure elements are typically found during a discovery process initiated when the NFC controller is up and running. For a given NFC chipset there can be many configurations (embedded SE or not, with or without a SIM card wired to the NFC controller SWP interface, etc...) and thus driver code will never know before hand which SEs are available. So we remove this field, it will be replaced by a real SE discovery mechanism.
