There are some issues with the b43_gpio_init() method in b43 [0], [1], [2], [3]. When I compare the spec [4] with the code in brcmsmac brcms_c_gpio_init() it is very different. Is this spec still correct for the recent ucode versions e.g. 666.2?

Quoted 1 line

Start with a GPIO Mask value of 0x1F and GPIO Set value of 0xF (Note >

that 0xF corresponds with the LEDs GPIO pins).
This is strange to me, shouldn't only the gpios used by this wifi chip be activated?
