From 8f166e00196fcb16364c9c39dab6fe7b72e63f18 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Thu, 16 Oct 2014 14:59:41 -0400 Subject: tty: Remove tty_pair_get_tty()/tty_pair_get_pty() api tty_pair_get_pty() has no in-tree users and tty_pair_get_tty() has only one file-local user. Remove the external declarations, the export declarations, and declare tty_pair_get_tty() static.
