libcamera: yaml_parser: Return nullopt on error from YamlObject::get()
The YamlParser::get<>() function returns an std::optional<> to indicate
when YAML parsing failed.
The current implementation returns a default constructed std::optional
in case of errors with
return {};
This has been reported as generating compiler warnings with a gcc 9.3.0
arm64 cross-compiler:
../src/libcamera/yaml_parser.cpp:184:11: error: ‘<anonymous>’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
184 | return {};
| ^
Replace this with an explicit
return std::nullopt;
which fixes the warnings and conveys the purpose more explicitly.
