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).
