I find the resulting version a bit confusing:

	if (Offset >= EFUSE_MAX_HW_SIZE)
		return false;
	/* DbgPrint("Read fake content, offset = %d\n", Offset); */
	if (fakeEfuseBank == 0)
		*Value = fakeEfuseContent[Offset];

The check on "Offset" isn't separated in any way by the following
logic. I would suggest that you replace the closing brace by a newline,
also for the other cases you're fixing up here:

	if (Offset >= EFUSE_MAX_HW_SIZE)
		return false;

	/* DbgPrint("Read fake content, offset = %d\n", Offset); */
	...
