From 60cd06e13c32c569a03bb7b4a872b770c2b7813a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Peter=20K=C3=BCmmel?= Date: Sat, 29 Nov 2014 17:26:04 +0900 Subject: [PATCH] =?utf8?q?kconfig:=20Fix=20warning=20"=E2=80=98jump?= =?utf8?q?=E2=80=99=20may=20be=20used=20uninitialized"?= MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Warning: In file included from scripts/kconfig/zconf.tab.c:2537:0: scripts/kconfig/menu.c: In function ‘get_symbol_str’: scripts/kconfig/menu.c:590:18: warning: ‘jump’ may be used uninitialized in this function [-Wmaybe-uninitialized] jump->offset = strlen(r->s); Simplifies the test logic because (head && local) means (jump != 0) and makes GCC happy when checking if the jump pointer was initialized.
