Instead of having a platform device defined in a devices.c and register it in the machine file allocate it dynamically. This reduces the size of needed memory as the new function is discarded after init and only the existing devices are created. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
