Subject: bcma: trouble with gpio

Hi,
I turned GPIO support in bcma (CONFIG_BCMA_DRIVER_GPIO)
and get this in log:
bcma: bus0: Found chip with id 0xA8D8, rev 0x01 and package 0x0A

gpiochip_add: gpios -1..14 (bcma_gpio) failed to register
bcma: bus2: Error registering GPIO driver: -28
bcma: bus2: Bus registered
does that mean that gpio is not usable?
what might be the problem?
Kind regards
Piotr
