This fixes the following compile warning:
drivers/serial/8250.c: In function 'serial8250_init':
drivers/serial/8250.c:2963: warning: unused variable 'i'
that was introduced by b70ac771 (serial: allow 8250 to be used on sparc)
that removed the last use of the variable.

I find those code in this function __init serial8250_init(void)
for (i = 0; i < NR_IRQS; i++)
spin_lock_init(&irq_lists[i].lock);
So you do not remove the 'i'.

Look at the referenced commit b70ac771 (serial: allow 8250 to be used on
sparc). It is quite recent (Mon Oct 13 10:36:31 2008 +0100), but if you
pull Linus' latest tree it is there.
