+Subject: [PATCH] cfg80211: fix a type issue in
+ ieee80211_chandef_to_operating_class()
+
+The "chandef->center_freq1" variable is a u32 but "freq" is a u16 so we
+are truncating away the high bits.  I noticed this bug because in commit
+9cf0a0b4b64a ("cfg80211: Add support for 60GHz band channels 5 and 6")
+we made "freq <= 56160 + 2160 * 6" a valid requency when before it was
+only "freq <= 56160 + 2160 * 4" that was valid.  It introduces a static
+checker warning:
+
+    net/wireless/util.c:1571 ieee80211_chandef_to_operating_class()
+    warn: always true condition '(freq <= 56160 + 2160 * 6) => (0-u16max <= 69120)'
+
+But really we probably shouldn't have been truncating the high bits
+away to begin with.
