Hm, can you reverse the srcreg/destreg order?
All C-standard copy functions use func(dest, src).
I think we should stick with it.

Lots of whitespace needed here...

^^ ^ ^
b43_hf_read is not called. You OR the function pointer.
And whitespace at the wrong spot.

Any chance to define a name for the register?
Even if it's just B43_LPPHY_030 or something like that.

Lots of whitespace problems in this code block.
And please define the registers. Even if you just assign numeric names (like above).
(hint: also use the B43_PHY_OFDM() macro)
