Error of RBTreeDecrement function about eastl HOT 3 CLOSED

Furthermore, there is a mistake in the comment for the RBTreeDecrement function, where it is written as RBTreeIncrement function.

You'll have to explain the issue you have further. RBTreeDecrement is an EASTL internal function - it shouldn't be called by users.

If you have a case that is calling RBTreeDecrement when there is no previous elements then it's likely that you are using the container/iterator incorrectly - such as calling decrement on an iterator that is equal to begin(). In such cases EASTL behaviour is undefined. If you meeting the container & iterator requirements and believe there is an issue with rbtree please provide a small reproducible example of the issue.

ummm...., this is indeed discussing an undefined behavior, I'm very sorry about this and I will close this issues. But it may be avoidable, because there is no predecessor node to the root node of the tree structure, and it is more reasonable to return end() for this.
