I fixed up a couple of typos and added the missing negation above so
that it reads:

  The debug printk() in digi_write() prints in_interrupt() as context
  information. This information is imprecise as it does not distinguish
  between hard-IRQ or disabled bottom half and it does not consider
  disabled interrupts or preemption. It is not really helpful.
