  - dev: interrupt: arm_gic: Fix ubsan error
    
    Bug: 297275002
    Change-Id: I40826d18011c95ce52bdf0fa7978ba6f034bb5c6
    
  - binary_search_tree: Add missing type check for bst_search_type
    
    The caller passed an item to bst_search_type that did not match the
    specified type without getting a compile error as long as item also had
    a member with the same name. As a result the compare function would get
    a pointer passed to an object with the wrong type.

  - binary_search_tree: Add search by key instead of node
    
    Add api to search for a node without providing a temporary node struct.
