From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx> The commit "ath9k: Fix IQ calibration" added a check to ensure that valid i2_p_q2_a0_d1 values are not discarded. But since it is masked with 0xfff earlier, the codepath will not be executed. The earlier case where all values above 0x800 were considered invalid is incorrect, since the HW can return valid values between 0x800 and 0xfff.
