Subject: analysis: None used in pointer context
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ec59af290cfd6813ff4df37994067de5cea2f1c4;p=profile%2Fivi%2Fclutter.git

analysis: None used in pointer context

While this is totally fine (None is 0L and, in the pointer context, will
be converted in the right internal NULL representation, which could be a
value with some bits to 1), I believe it's clearer to use NULL instead
of None when we talk about pointers.
