From 5dca607bcf10d3f08d07ffeac664c6769c336145 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 16 Jun 2009 17:01:02 +0100 Subject: tty: fix unused warning when TCGETX is not defined MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If TCGETX is not defined, we end up with this warning: drivers/char/tty_ioctl.c: In function ‘tty_mode_ioctl’: drivers/char/tty_ioctl.c:950: warning: unused variable ‘ktermx’ Since the variable is only used in one case statement, push it down to the local case scope.
