+Subject: mac80211: initialize variable have_higher_than_11mbit
+
+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")
