Subject: gpiolib: make gpiochip_add() show a better error message
X-Git-Tag: v2.6.35-rc1~215

gpiolib: make gpiochip_add() show a better error message

The current message, 'not registered' is confusing as it implies it was
not registered with something, whereas printing 'failed to register'
implies it was the gpiochip_add() call that did not work correctly.
