firewire: core: add KUnit test skeleton for node tree Some issues have been reported in node tree management. Refactoring the topology-related code in the core is required. Adding unit tests would help ensure that the refactoring does not introduce regressions. This commit adds a KUnit test skeleton for this purpose.

firewire: core: add KUnit tests for successful tree building After a bus reset, self ID sequence is captured by 1394 OHCI hardware and passed to software through SelfID DMA context. The core parses the sequence to build an internal cache of the node tree for the current generation of the bus. This is the first step in managing resources on the bus. The tree is build by the build_tree() function. This commit adds KUnit tests for the function, covering several successful scenarios.

firewire: core: add KUnit tests for failure of tree building Abdun Nihaal has reported a memory leak when tree building fails in the middle of self ID sequence enumeration. This is caused by an invalid self ID sequence and is not a common occurrence. This commit is intended to assist in fixing the issue by adding KUnit tests to show the cases in which the memory leak is triggered. The leak occurs internally in the build_tree() function, therefore it cannot be detected directly by the tests.
