Subject: [PATCH 01/15] wifi: ieee80211: check for NULL in ieee80211_mle_size_ok()
Date: Mon, 18 Mar 2024 18:53:17 +0200	[thread overview]
Message-ID: <20240318184907.4d983653cb8d.Ic3ea99b60c61ac2f7d38cb9fd202a03c97a05601@changeid> (raw)
In-Reply-To: <20240318165331.3170594-1-miriam.rachel.korenblit@intel.com>

From: Johannes Berg <johannes.berg@intel.com>

For simplicity, we may want to pass a NULL element, and
while we should then pass also a zero length, just be a
bit more careful here.
