[patch 041/108] serial: bfin_5xx: add missing spin_lock init

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Mike Frysinger <vapier@xxxxxxxxxx>

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.
