[PATCH 02/15] serial: bfin_5xx: add missing spin_lock init

From: Alan Cox
Date: Mon Jun 22 2009 - 12:39:26 EST


From: Mike Frysinger <vapier@xxxxxxxxxx>

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.
