From 310ae37edb3becedf5da904201f3439ea42ab12f Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 25 Aug 2015 17:09:40 +0200 Subject: Fix bad return value checks (detected with Coccinelle) In the "Getting Started with Coccinelle - KVM edition" presentation that has been held by Julia Lawall at the KVM forum 2015 (see the slides at http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf), she pointed out some bad return value checks in U-Boot that can be detected with Coccinelle by using the following config file: @@ identifier x,y; identifier f; statement S; @@ x = f(...); ( if (x < 0) S | if ( - y + x < 0) S ) This patch now fixes these issues.
