Subject: [PATCH 4.9 06/21] mac80211: initialize variable have_higher_than_11mbit
Date: Mon, 10 Jan 2022 08:22:53 +0100 [thread overview]
Message-ID: <20220110071813.022371698@linuxfoundation.org> (raw)
In-Reply-To: <20220110071812.806606886@linuxfoundation.org>
From: Tom Rix <trix@redhat.com>
commit 68a18ad71378a56858141c4449e02a30c829763e upstream.
Clang static analysis reports this warnings
mlme.c:5332:7: warning: Branch condition evaluates to a
garbage value
have_higher_than_11mbit)
^~~~~~~~~~~~~~~~~~~~~~~
have_higher_than_11mbit is only set to true some of the time in
ieee80211_get_rates() but is checked all of the time. So
have_higher_than_11mbit needs to be initialized to false.
Fixes: 5d6a1b069b7f ("mac80211: set basic rates earlier")
