If no platform_data was givin to the device it's going to use it's default platform data struct which has all fields initialized to zero. As a result the driver is going to try to request gpio0 both as write protect and card detect pin. Which of course will fail and makes the driver unusable Previously to the introduction of no_wprotect and no_detect the behavior was to assume that if no platform data was given there is no write protect or card detect pin. This patch restores that behavior.
