From 9c529a3d76dffae943868ebad07b042d15764712 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 22 Jun 2009 18:37:24 +0100 Subject: [PATCH] serial: bfin_5xx: add missing spin_lock init The Blackfin serial driver never initialized the spin_lock that is part of the serial core structure, but we never noticed because spin_lock's are rarely enabled on UP systems. Yeah lockdep and friends.
