[libcamera-devel] [PATCH v2 2/2] test: controls: control_info_map: Test default constructor

[Mattijs Korpershoek]

ControlInfoMap can be default-constructed. In that case, some of its
members (like idmap_) can be a nullptr, and ControlInfoMap.find() will segfault.

Add a test with a default constructed ControlInfoMap to cover this.
