Input: pcf8574_keypad - fix error handling in pcf8574_kp_probe It is not allowed to call input_free_device() after calling input_unregister_device() because input devices are refcounted and unregister will free the device if we were holding he last referenc. The preferred style in input/ is to make input_register_device() the last function in the probe which can fail. That way we don't need to call input_unregister_device(). Also do not need to call input_set_drvdata() as nothing in the driver uses the data. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
