Hi All, I just noticed these errors in my dmesg after toggling rfkill on/off on a Lenovo yoga 300-11ibr. Note this device has a firmware rfkill interface which results in the rfkill pin on the card actually being toggled (the phy0 rfkill shows up as hardblocked when softblock is set on the firmware interface).
