NAME
       subsys_dev_iter_init - initialize subsys device iterator

SYNOPSIS
       void subsys_dev_iter_init(struct subsys_dev_iter * iter, struct bus_type * subsys, struct device * start, const struct device_type * type);

ARGUMENTS
       iter
	   subsys iterator to initialize

       subsys
	   the subsys we wanna iterate over

       start
	   the device to start iterating from, if any

       type
	   device_type of the devices to iterate over, NULL for all

DESCRIPTION
