`sdw_of_find_slaves()` fetches raw `"compatible"` bytes with
`of_get_property()` and then immediately parses them with
`sscanf("sdw%01x%04hx%04hx%02hhx", ...)`.
Live-tree OF properties are stored as raw bytes plus a separate length;
they are not globally guaranteed to be NUL-terminated. Validate the
first compatible string before parsing it.
