Pull firewire updates from Takashi Sakamoto:

 - Guarantee asynchronous packet and transaction callbacks in process
   context

   Both the 1394 OHCI driver and the core transaction layer have been
   changed to guarantee that asynchronous packet and transaction
   callbacks are invoked in process context. In v6.17, the execution
   context depended on the transaction destination: callbacks for
   transactions destined for remote nodes were invoked from a workqueue,
   whereas callbacks for transactions destined for the local node or
   terminated due to internal errors were invoked in the transaction
   initiator's context.

   All such callbacks are now guaranteed to execute in process context,
   eliminating the need to account for different execution contexts when
   implementing callback functions.

 - Fill kerneldoc for transaction layer

   The above change guarantees a consistent execution context for packet
   and transaction callbacks, making it possible to document their
   execution context in kerneldoc.

 - Enable compiler-based context analysis for the transaction layer

   The core transaction layer is sufficiently complex that
   compiler-based context analysis can help detect invalid call paths.

 - Fix a reference count leak in the cdev layer

   A reference count leak was reported when a user space application
   delegated isochronous resource management. This issue has now been
   fixed.

 - Add KUnit tests for the configuration ROM parser and generator

   In recent years, questions have been raised about how the
   configuration ROM parser and generator handle boundary conditions and
   edge cases. KUnit tests have been added to verify their behavior in
   these situations. KUNIT_STATIC_STUB_REDIRECT is used to stub the
   transaction responder so that it returns the configuration ROM
   contents.

 - Misc fixes for kerneldoc and nosy-dump application
