[Qemu-devel] [PATCH] qjson.h: Remove spurious GCC_FMT_ATTR markup from qobject_from_json() declaration |

The function qobject_from_json() doesn't actually allow its
argument to be a format string -- it passes a NULL va_list*
to qobject_from_jsonv(), and the parser code will then never
actually intepret %-escape sequences (it tests whether the
va_list pointer is NULL and will stop with a parse error).
The spurious attribute markup causes clang warnings in some
of the test cases where we programmatically construct JSON
to feed to qobject_from_json():
tests/test-qmp-input-visitor.c:76:35: warning: format string is not a
string literal (potentially insecure) [-Wformat-security]
data->obj = qobject_from_json(json_string);
^~~~~~~~~~~
Remove the incorrect attribute.
