[patch 16/16] parport/ieee1284_ops: replace schedule_timeout() with ms

I would appreciate any comments from the janitor@sternweltens list. This is one 
(of
many) cases where I made a decision about replacing

set_current_state(TASK_INTERRUPTIBLE);
schedule_timeout(some_time);

with

msleep(jiffies_to_msecs(some_time));

msleep() is not exactly the same as the previous code, but I only did
this replacement where I thought long delays were *desired*. If this is
not the case here, then just disregard this patch. 

Thanks,
Nish



Description: Uses msleep() instead of schedule_timeout() to guarantee
the task delays the desired time.
