Typo in commit title: retrieve

-	if (!cfg80211_chandef_valid(&mac->chandef)) {
-		pr_err("invalid channel settings on %s\n", ndev->name);
-		return -ENODATA;
+	if (!cfg80211_chandef_valid(chandef)) {
+		pr_err("%s: bad chan freq1=%u bw=%u\n", ndev->name,
+		       chandef->center_freq1, chandef->width);
+		ret = -ENODATA;
 	}

Lets keep both center_freq1 and center_freq2 in error message.
