    Pull firewire updates from Takashi Sakamoto:

     - firewire drivers have been able to assign an arbitrary value in the
       mod_device entry, which is typed as kernel_ulong_t.

       While storing the pointer value is legitimate, conversion back to a
       pointer has been performed without preserving the const qualifier.

       Uwe Kleine-König introduced an union to provide safer and more robust
       conversions, as part of the ongoing CHERI enhancement work for ARM
       and RISC-V architectures. This includes changes to the sound
       subsystem, since the conversion pattern is widely used in ALSA
       firewire stack.

     - Userspace applications can request the core function to perform
       isochronous resource management procedures. Dingsoul reported a
       reference-count leak when these procedures are processed in workqueue
       contexts.

       This refactors the relevant code paths following a divide and conquer
       approach. Consequently, it became clear that the issue still remain
       in the path when userspace applications delegate automatic resource
       reallocation after bus resets to the core.

       In practice, the leak is rarely triggered, and a complete fix is
       still in progress.
