Subject: mac80211-hwsim: remove unnecessary hwname check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b67e01fc0c4f7759a3e6e75fdcf17195daa482e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
