The test cases cover the following scenarios:
- Basic: Verifies that a consumer can successfully access the resource
provided via the provider.
- Revocation: Verifies that after the provider revokes the resource,
the consumer correctly receives a NULL po... | ```diff

Some resources can be removed asynchronously, for example, resources
provided by a hot-pluggable device like USB. When holding a reference
to such a resource, it's possible for the resource to be removed and
its memory freed, leading to use-after-free errors on subsequent access.
The "revocable" mech... | ```diff

Extend the QMI byte encoding and decoding logic to support multiple basic
