Why isn't this device exposed via device_get_binding()?

[endian-benjamin]

drivers/modem/gsm_ppp.c has the following init macro:

DEVICE_INIT(gsm_ppp, "modem_gsm", gsm_init, &gsm, NULL, POST_KERNEL,
	    CONFIG_MODEM_GSM_INIT_PRIORITY);

which for some reason doesn't lead to a device struct that is findable by neither the device shell nor device_get_binding(). Why is this and how do we make it findable?

Answering my own question here:

device_get_binding only returns properly inited devices. The way it checks if it's inited is by checking if it has an API. Thus, devices without APIs doesn't get reported.
