+Subject: NFC: Use dynamic initialization for rwlocks
+
+From: Szymon Janc <szymon.janc@tieto.com>
+
+commit fe235b58d517d623bf6d40c77afca1b0ee6fc85d upstream.
+
+If rwlock is dynamically allocated but statically initialized it is
+missing proper lockdep annotation.
+
+INFO: trying to register non-static key.
+the code is fine but needs lockdep annotation.
+turning off the locking correctness validator.
