If any of the p54-based drivers are built with CONFIG_P54_LEDS not
defined, the following warning is generated:

  CC [M]  drivers/net/wireless/p54/main.o
drivers/net/wireless/p54/main.c: In function ‘p54_register_common’:
drivers/net/wireless/p54/main.c:614:21: warning: unused variable ‘priv’

V2 - use __maybe_unused instead of conditional compilation

well, there is a third option [use the priv in the dev_info)
However, this approach is fine too.

BTW, John... What's your ?WG511? doing?
