Merge tag 'firewire-fixes-6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394
Pull firewire fix from Takashi Sakamoto:
"A single patch to fix long-standing issue of memory leak at failure of
device registration for fw_unit. We rarely encounter the issue, but it
should be applied to stable releases, since it fixes inappropriate API
usage"
* tag 'firewire-fixes-6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394:
