Hi,
Russell, sorry if you are not responsible for this driver, but I figure
the more eyes the better.

Please consider applying.
Description: Use msleep_interruptible() instead of schedule_timeout() in
send_break() to guarantee the task delays as expected. Change
@duration's units to milliseconds, and modify arguments in callers
appropriately.
