One of the goals of having less boilerplate on QOM declarations
is to avoid human error. Requiring an extra argument that is
never used is an opportunity for mistakes.
Remove the unused argument from OBJECT_DECLARE_TYPE and
OBJECT_DECLARE_SIMPLE_TYPE.
Coccinelle patch used to convert all users of the macros:
@@
declarer name OBJECT_DECLARE_TYPE;
identifier InstanceType, ClassType, lowercase, UPPERCASE;
@@
OBJECT_DECLARE_TYPE(InstanceType, ClassType,
- lowercase,
UPPERCASE);
@@
declarer name OBJECT_DECLARE_SIMPLE_TYPE;
identifier InstanceType, lowercase, UPPERCASE;
@@
OBJECT_DECLARE_SIMPLE_TYPE(InstanceType,
- lowercase,
UPPERCASE);
