* leds: various: use only available OF childrenMarek Behún2020-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various drivers count and iterate over OF children nodes via of_get_child_count and for_each_child_of_node. Instead they should use of_get_available_child_count and for_each_available_child_of_node, so that if a given node has the `status` property set to `disabled`, the child will be ignored.
