From 7b948f1377322b0b95feee62e307b6889a09e4ea Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Fri, 14 Jul 2017 22:04:49 +0530 Subject: auxdisplay: constify charlcd_ops. charlcd_ops are not supposed to change at runtime. All functions working with charlcd_ops provided by work with const charlcd_ops. So mark the non-const structs as const.
