are there any void initcalls ?  or just ones where you ignore the value ?  
otherwise we can simply rename DO_INITCALL_RET() to DO_INITCALL().

#define DO_INITCALL_RET(x, ...) \
	({ \
		int __ret; \
		printf("calling  0x%pF\n", x); \
		__ret = (x)(__VA_ARGS__); \
		printf("initcall 0x%pF returned\n", x); \
		__ret; \
	})
