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.

[Note: not tested, I don't have the H/W]

I think this needs review from someone familiar with the hardware.

Patch set to Changes Requested.
What "change" are you requesting here?
Don't take patchwork states literally, a better name for this state
would be "Needs work" or something like that.
Likely there needs to be some other setting for the patch.

Perhaps "deferred" as you seem to be requesting a review
and there's no actual change necessary, just approval from
someone with the hardware and that someone test the patch.
I already asked for help on April 7th and nobody replied, so I'm
dropping this now. The patch can be resent if/when the change is
confirmed to be correct.
