      wifi: rtw89: 8852a: rfk: fix div 0 exception · 683a4647
      Ping-Ke Shih authored
      The DPK is a kind of RF calibration whose algorithm is to fine tune
      parameters and calibrate, and check the result. If the result isn't good
      enough, it could adjust parameters and try again.
      
      This issue is to read and show the result, but it could be a negative
      calibration result that causes divisor 0 and core dump. So, fix it by
      phy_div() that does division only if divisor isn't zero; otherwise,
      zero is adopted.

      wifi: rtw89: disable invalid phy reports for all ICs · 47324ab6
      Po-Hao Huang authored
      Previously we only disable invalid reports for 52A, since we plan to
      support more ICs in the future, enable settings for those as well.
