  firewire: core: fix memory leak in error path of build_tree() (2026-08-12 07:50:06 +0900)

----------------------------------------------------------------
firewire updates for v7.3

This update includes error checks, a potential bug fix, and KUnit tests.

Sreeraj S Kurup addressed an error case when generating the contents of
the configuration ROM with parameters supplied by in-kernel
implementations such as unit drivers. Some error checks were added to
handle failures in this path.

Abdun Nihaal identified a potential memory leak when an invalid self-ID
sequence causes an error while building the internal node tree. KUnit
tests have been added to trigger this case. This memory leak has existed
since the first commit and has now been fixed.
