ath6kl_usb_submit_ctrl_in() did not take into account the situation where
the length of the data read from the device is not equal to the len, and
such missing judgments will result in subsequent code using incorrect data.

usb_control_msg_recv() handles the abnormal length of the returned data,
so using it directly can fix this warning.

Did you test this on real ath6kl hardware?
