[PATCH 00/15] random tty fixes

[Jiri Slaby (SUSE)]

This is a collection of random fixes for tty I did while crawling
through the code. Mostly done for readability and understandability. No
behavior change intended (except for Documentation fixes).

Jiri Slaby (SUSE) (15):
  tty: n_tty: use 'retval' instead of 'c'
  tty: n_tty: rename and retype 'retval' in n_tty_ioctl()
  tty: n_tty: use min3() in copy_from_read_buf()
  tty: n_tty: invert the condition in copy_from_read_buf()
  tty: n_tty: use do-while in n_tty_check_{,un}throttle()
  tty: switch tty_{,un}throttle_safe() to return a bool
  tty: invert return values of tty_{,un}throttle_safe()
  tty: fix up and plug in tty_ioctl kernel-doc
  tty: fix kernel-doc for functions in tty.h
  tty: stop using ndash in kernel-doc
  tty: tty_buffer: use bool for 'restart' in
    tty_buffer_unlock_exclusive()
  tty: convert THROTTLE constants into enum
  tty: early return from send_break() on TTY_DRIVER_HARDWARE_BREAK
  tty: don't check for signal_pending() in send_break()
  tty: use 'if' in send_break() instead of 'goto'
