There is a warning while building JSON extension code:
ovs/_json.c: In function 'json_to_python':
ovs/_json.c:121:49:
warning: passing argument 1 of 'json_to_python' discards 'const'
qualifier from pointer target type [-Wdiscarded-qualifiers]
121 | PyObject *item = json_to_python(json_array_at(json, i));
| ^~~~~~~~~~~~~~~~~~~~~~
ovs/_json.c:81:29: note: expected 'struct json *' but argument is
of type 'const struct json *'
81 | json_to_python(struct json *json)
| ~~~~~~~~~~~~~^~~~
The warning can be seen in the CI job for the debian package build.
Fixes: 1de4a08c220c ("json: Use functions to access json arrays.")
