From 541e68e0c3d0be9a940632edc5181788fff11d88 Mon Sep 17 00:00:00 2001 From: Gargi Sharma Date: Sun, 5 Mar 2017 15:21:44 +0530 Subject: [PATCH] staging: dgnc: Constify ktermios structure The ktermios structure is a local default termios struct. All ports are initially created with this termios. Since, the structure is never modified, it can be declared as const.
