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: firewire: core: fix possible memory leak in create_units()
