Subject: ath9k: avoid ANI restart if no trigger
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c1cab1df9b651d999922e0f04d01dc046121a237;p=linux-beck.git

ath9k: avoid ANI restart if no trigger

Fixes commit 54da20d83f0e ("ath9k_hw: improve ANI processing and rx desensitizing parameters")

Call ath9k_ani_restart() only when the phy error rate reach the
ANI immunity threshold. Sync the logic with internal code base.
