2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Mike Frysinger commit 9c529a3d76dffae943868ebad07b042d15764712 upstream. 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.
