The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

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

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.
	

Remove the in_interrupt() printout.

v2…v3:
  - Don't make dev_dbg() conditional on `tty'
  - Remove the part "tty happens always in process context" from the
    commit message. Johan pointed out that for PPP it may happen in
    bottom half.

Now applied for -next, thanks.

Johan
