That's not related or (as far as I can tell) especially harmful. If you look at the referenced line of code (net/wireless/core.c, line 363) you see it's a message generated because we have a set_tx_power function without a get_tx_power function. (The second message is the same; but for get_antenna). I suspect you're seeing it because you've updated your driver and/or firmware.
