Subject: [PATCH 1/2] nl80211: don't return err unconditionally in nl80211_start_ap()
Date: Fri, 26 Jun 2020 12:49:39 +0300	[thread overview]
Message-ID: <iwlwifi.20200626124931.871ba5b31eee.I97340172d92164ee92f3c803fe20a8a6e97714e1@changeid> (raw)

From: Luca Coelho <luciano.coelho@intel.com>

When a memory leak was fixed, a return err was changed to goto err,
but, accidentally, the if (err) was removed, so now we always exit at
this point.

Fix it by adding if (err) back.
