+Subject: [PATCH] mac80211: minstrel_ht: fix regression in the max_prob_rate
+ fix
+
+Since mi->max_prob_rate is overwritten after the loop that calls
+minstrel_ht_set_best_prob_rate, the new best rate needs to be written to *dest
+
+Fixes: a7fca4e4037f ("mac80211: minstrel_ht: fix max probability rate selection")
