Subject: [PATCH] mac80211: IBSS: avoid unneeded return value processing
Date: Wed, 11 Sep 2019 16:14:31 +0200 [thread overview]
Message-ID: <20190911141431.12498-1-koen.vandeputte@ncentric.com> (raw)
when ieee80211_ibss_csa_beacon() fails, we return it's value.
When it succeeds, we basically copy it's value and also .. return it.
Just return it immediately, simplifying the code.
