This sort of loop is normally either handled by indexing up to a limit
(ARRAY_SIZE, in this case) or by iterating until hitting a sentinel
(NULL, in this case). It is redundant to use both, as this code does.
The former (using ARRAY_SIZE) is typically employed when you know the
number of items upfront, such as when the item list is local and
compiled in; the latter (NULL sentinel) is typically used when
receiving an item list as an argument to a function where you don't
know the item count upfront (and the item count is not passed to the
function as a separate argument).
In this case, the item list is local and its size is known to the
compiler, so that suggests using ARRAY_SIZE, and dropping the NULL
sentinel.
Style aside: This 'if' statement is very wide and likely should be
wrapped over multiple lines (trying to keep the code within an
80-column limit).

Style:
Drop spaces inside 'if' parentheses.
Place warning() on its own line.
