-Subject: [PATCH] ath10k: Ensure peer_map references are cleaned up.
-
-While debugging OS crashes due to firmware crashes, I enabled
-kasan, and it noticed that peer objects were being used-after-freed.
-
-Looks like there are two places we could be leaving stale references
-in the peer-map, so clean that up.
