Initialize class device iterator
void class_dev_iter_init(struct class_dev_iter * iter, struct class * class, struct device * start, const struct device_type * type);
iter
class iterator to initialize
class
the class 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
Initialize class iterator iter such that it iterates over devices of class. If start is set, the list iteration will start there, otherwise if it is NULL, the iteration starts at the beginning of the list.
