drivers/ieee1394/ieee1394_transactions.c fails for me if CONFIG_SMP=n

I fixed this by adding #include <linux/sched.h> before #include <linux/wait.h>
But that is probably not the correct fix, but gives me a working kernel.

Diff between a working .config and a failing one:
(created by switching SMP off with menuconfig)
