Hi,

this is again a series of various TTY cleanups. The stats say: 116 files
changed, 661 insertions, 2602 deletions. The major part of the removal
is a drop of BROKEN r3964 ldisc. The rest is mostly removal of dead
code, or adaption to the current tty core state.

Jiri Slaby (35):
tty: remove broken r3964 line discipline
n_tty: remove n_tty_receive_char wrapper
n_tty: remove n_tty_receive_char_fast
n_tty: drop n_tty_receive_buf_fast

n_tty: move lnext handling
n_tty: make n_tty_receive_char_special return void
n_tty: do only one cp dereference in n_tty_receive_buf_standard
n_tty: invert TTY_NORMAL condition in n_tty_receive_buf_standard
n_tty: remove superfluous return from n_tty_receive_signal_char

tty: remove tty_operations::chars_in_buffer for non-buffering
tty: make tty_operations::chars_in_buffer return uint
serial: make usb_serial_driver::chars_in_buffer return uint
nozomi: simplify ntty_chars_in_buffer
