Subject: [PATCH] net: wireless: b43legacy: radio.c: Remove unused function

Remove the function b43legacy_radio_set_tx_iq() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

Alternatively...

"b43legacy: Remove unused function in radio.c"

BTW, as Arnd Bergmann pointed out [1] how did you test with cppcheck
to get such stuff?

It seems to be for A-PHY based hardware (with 0x2060 radio id) which
is not handled by b43legacy. Should be safe to drop this code (we
won't likely need it).

For future, we prefix patches with just a driver name. So this could
be simply called
b43legacy: radio.c: Remove unused function
