From 01e55dc353f7757f1a50e2c55bc9c699f3403109 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Mon, 23 May 2011 18:39:17 +0400 Subject: [PATCH] kvm tools: Drop unused vars from int10.c code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There is a couple of functions which defines 'ah' variable but never use it in real so that gcc 4.6.x series does complain on me as CC bios/bios-rom.bin bios/int10.c: In function ‘int10_putchar’: bios/int10.c:86:9: error: variable ‘ah’ set but not used [-Werror=unused-but-set-variable] bios/int10.c: In function ‘int10_vesa’: bios/int10.c:96:9: error: variable ‘ah’ set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors so get rid of them.
