From a180d023ec7ba0e43b2385876950d9ce7ab618f1 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Mon, 19 Aug 2019 13:21:26 +0530 Subject: auxdisplay: ht16k33: Make ht16k33_fb_fix and ht16k33_fb_var constant The static structures ht16k33_fb_fix and ht16k33_fb_var, of types fb_fix_screeninfo and fb_var_screeninfo respectively, are not used except to be copied into other variables. Hence make both of them constant to prevent unintended modification. Issue found with Coccinelle.
