hvc_console: replace schedule_timeout()

PATCH 1/1 hvc_console: replace schedule_timeout()
I would appreciate any comments from the janitors 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
Applys-to: 2.6.7
Description: Uses msleep() instead of schedule_timeout() to guarantee the task delays at least the desired time amount.
