+Subject: [PATCH] mac80211: minstrel_ht: fix infinite loop because supported is
+ not being shifted
+
+Currently the for-loop will spin forever if variable supported is
+non-zero because supported is never changed.  Fix this by adding in
+the missing right shift of supported.
+
+Addresses-Coverity: ("Infinite loop")
+Fixes: 48cb39522a9d ("mac80211: minstrel_ht: improve rate probing for devices with static fallback")
