Actually, after taking another look at this, I don't think that using 
comedi_timeout()
here is going to work, actually.
The context from which s626_send_dac() is called allows sleep all right, but 
readl() isn't
a comedi function and therefore it doesn't behave (in parameters or return 
values) as
the callback function parameter to comedi_timeout() requires.  So unless I'm 
missing
something particularly large here, I believe we'll have to do the timeouts here 
manually
as well.  Am I correct here, and if so, would you like the iteration based 
timeouts here
as well, or a sleep-based timeout similar to that employed by comedi_timeout()?


Thanks,
Chase
