Greg and Kay,
The wireless driver b43legacy uses a leds-class entry to interact with the
rfkill subsystem to control the radio LED. The name under which the LED is
registered is "b43legacy-phy0::radio", which is 21 characters in length. When
the corresponding directory is created in sysfs, the name is truncated to 19
characters due to the "#define BUS_ID_SIZE 20" statement in include/linux/device.h.
Marcel Holtmann wrote that he understood that this limitation will be
eliminated, and suggested that I contact you regarding this matter. I was
thinking of changing the driver so as to be able to control the naming; however,
if this limitation will be relaxed then I will just wait.
Thanks,
Larry

The limit is gone already:
