From d0c4e39d12f903e06db262656cff2e24d267bed7 Mon Sep 17 00:00:00 2001

From: Kevin Cernekee <cernekee@chromium.org>

|
||||
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_timeout_* are not exported to library
|
||||
callers.
|
||||
|
||||
Move the attribute up into the function definition to make clang happy.
