From: Colin Ian King <colin.king@xxxxxxxxxxxxx> The calculation of offtune_val seems incorrect, the u16 value in pi->tx_rx_cal_radio_saveregs[2] is being masked with 0xf0 and then shifted 8 places right so that always ends up as a zero result. I believe the intended shift was 4 bits to the right. Fix this.
