Hrm, it is but this points out an error in the control helpers which has
been there since forever - they call that parameter max but it's not a
maximum, it's the number of elements in the enumeration. I bet we have
a bunch of other enumerations which miss the last element as a result.
Yeah, the argument name is really confusing. I had to double-check
the code when I reviewed your patch, too :)
Also it'd be better to have a practice to use either ARRAY_SIZE() or a
constant there, too.
There is also SOC_ENUM_SINGLE_DECL(...) which takes care of the common case
where you want as many items as your array contains.
