From 61ab7903b8cd772d3bfb28bc26d02c599cfb0e5b Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Fri, 9 Sep 2005 13:10:02 -0700 Subject: [PATCH] fbdev: Initialize var structure in calc_mode_timings The var structure in calc_mode_timings is not properly initialized (zero set) which leads to undefined behavior when it is passed to fb_get_mode().
