This looks like an off-by-one test against
SMU_MSG_MAX_COUNT where type
should be >=

Perhaps instead it should be against ARRAY_SIZE(__smu_<foo>)

Also, the  __SMU_DUMMY_MAP macro is unnecessarily complex.

It might be better to have some direct
index and name struct like

struct enum_name {
	int val;
	const char *name;
};

And walk that.

Perhaps add a macro like

#define enum_map(e)
	{.val = e, .name = #e}
