Subject: [PATCH] mac80211: minstrel_ht: fix regression in the max_prob_rate fix
Date: Tue, 26 Jan 2021 16:44:09 +0100 [thread overview]
Message-ID: <20210126154409.6755-1-nbd@nbd.name> (raw)
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")
