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. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
