I'm not entirely sure what the preferred way of wrapping those comments 
is, but in other places in the comedi code we've been moving such 
comments to the previous line.

That comment really belongs inside the 'if' like this:

		if ((it->options[6] == 1) || (it->options[6] == 100)) {
			/* extended PCL718 to 100kHz DAC */
			devpriv->ns_min = 10000;
		}
