+From f58c5b09fb59baf07c942d373fc4d522b27e73c6 Mon Sep 17 00:00:00 2001
+From: Kevin Cernekee <cernekee@chromium.org>
+Date: Wed, 4 Jan 2017 14:30:26 -0800
+Subject: Use __EXPORTED rather than EXPORT_SYMBOL
+
+clang is sensitive to the ordering of
+__attribute__((visibility("default"))) relative to the function
+body. gcc is not. So if we try to re-declare an existing function
+with default visibility, clang prints a warning and generates
+a broken .so file in which nfct_helper_* are not exported to library
+callers.
+
+Move the attribute up into the function definition to make clang happy.
