   3 Subject: [PATCH] ath9k: avoid ANI restart if no trigger
   4
   5 Fixes commit 54da20d83f0e ("ath9k_hw: improve ANI processing and rx desensitizing parameters")
   6
   7 Call ath9k_ani_restart() only when the phy error rate reach the
   8 ANI immunity threshold. Sync the logic with internal code base.
