The task

**Symptom** When a driver defines its device API using `DEVICE_API_EXTENDS(base_api)`, the macro `DEVICE_API_IS(base_api, dev)` incorrectly returns false for instances obtained via `DEVICE_DT_GET`. Helper functions that gate on this check (e.g., `abstract_do_this()`, `abstract_do_that()`) consequently reject valid…
