There is nothing wrong with instance numbers and they are recommended for use whenever possible, but this is an API design problem because it's not always possible to get nodes by instance number; in some cases, drivers need to get node identifiers from node labels, for example. Change these APIs (which are not yet in any Zephyr release) to take node IDs instead of instance IDs. Fixes: #26984 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
