From a5f80e0a9a40732b9d7606ad369b288ce04cec29 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Tue, 6 Mar 2018 14:32:16 +1030 Subject: [PATCH] discover: Fix bad check of version string Clang says this: discover/device-handler.c:1564:27: warning: size argument in 'strncmp' call is a comparison [-Wmemsize-comparison] strlen(opt->version) == 0)) { ~~~~~~~~~~~~~~~~~~~~~^~~~ discover/device-handler.c:1563:5: note: did you mean to compare the result of 'strncmp' instead? strncmp(opt->version, tmp->version, ^ It looks like it's correct. However, we can go one better and drop the pointless strncmp(foo, bar, strlen(bar)), as this is equivalent to strcmp(foo, bar).
