Subject: [PATCH 0/3] tty: eliminate 64 byte stack buffers passed to tty_name

All users of tty_name pass the return value directly to a printf
function, so we might as well use tty->name directly instead of
copying it to a user-supplied (stack) buffer.

allmodconfig compile-tested only.

Rasmus Villemoes (3):
  tty: constify return type of tty_name
  tty: return tty->name directly from tty_name
  tty: remove buf parameter from tty_name()
