+    ath9k_htc: fix random decryption failure
+    
+    In v3.15 the driver stopped to accept network packets after successful
+    authentification, which could be worked around by passing the
+    nohwcrypt=1 module parameter.  This was not reproducible by
+    everyone, and showed random behaviour in some tests.
+    It was caused by an uninitialized variable introduced
+    in 4ed1a8d4a257 ("ath9k_htc: use ath9k_cmn_rx_accept") and
+    used in 341b29b9cd2f ("ath9k_htc: use ath9k_cmn_rx_skb_postprocess").
+
