It just limits those kconfig items to being =m or not set,
i.e., even though they are tristate, setting to =y is not
allowed.  I guess the thinking is that samples don't need to
reside in system memory for very long. However, if you want
this one to be capable of =y, like your patch, you can still
remove the end of the prompt string.
