Are these used? Would be nice to heave your best guess on the impact
this change will have in the commit message, for posterity scanning
git logs a few months/years from now.

BTW missing CC netdev, feel free to resend without 24h wait.

No impact. It's effectively a documentation fix.

I see ag71xx_wr(ag, AG71XX_REG_FIFO_CFG5, FIFO_CFG5_INIT); so yes, they're used.

That's embarrassing. Will do.
