Subject: mac80211_hwsim: clean up netlink exit code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf7a6b2d5bd73acd8e3a78cf03259489bd83498a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mac80211_hwsim: clean up netlink exit code

There's no need to print a message, and genl_unregister_family()
can't really fail so remove the error message there as well.
