From 6b67e01fc0c4f7759a3e6e75fdcf17195daa482e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 19 Nov 2014 18:51:55 +0100 Subject: [PATCH] mac80211-hwsim: remove unnecessary hwname check The hwname will always be set if idx is negative (as it's a u32 read into an s64 it can't overflow either) so we can remove the unnecessary check for hwname being non-NULL. This was reported by smatch.
