1 | by moving common code to ar5008_hw_cmn_spur_mitigate i forgot to move |
2 | mask_m & mask_p initialisation. This coused a performance regression | |
3 | on ar9281. | |

6 | Fixes: f911085ffa88 ("ath9k: split ar5008_hw_spur_mitigate and reuse common | |
7 | code in ar9002_hw_spur_mitigate.") | |
