[PATCH 0/7] n_tty fixes

[Peter Hurley <peter@hurleysoftware.com>]

This patch series combines a number of fixes for the N_TTY
line discipline.

These address unsafe use of the foreground process group id:
  n_tty: Fix unsafe driver-side signals
  n_tty: Lock access to tty->pgrp for POSIX job control

These continue Jiri's work to separate ldisc from tty:
  tty: Fix checkpatch errors in tty_ldisc.h
  n_tty: Encapsulate minimum_to_wake within N_TTY

The rest are self-explanatory:
  n_tty: Untangle read completion variables
  n_tty: Fix unsafe update of available buffer space
  n_tty: Buffer work should not reschedule itself
