[GIT PULL] firewire fixes for v6.7-rc4

[Takashi Sakamoto]

Hi Linus,

Please take this pull request for v6.7-rc4 release. It includes a slight
change to fix scarce memory leak.

As I noted in pull request for v6.7[1], Linux FireWire subsystem still
has an issue of unexpected system reboot in AMD Ryzen machine with a
kind of PCI card. Recently I got a help of AMD developer[2] and got some
advices to investigate the mechanism of system reboot, but never catch
its tail yet... I wish to fix it within the development period for v6.8
kernel.

firewire fixes for 6.7-rc4

This pull request includes a single patch to fix long-standing issue of
memory leak at failure of device registration for fw_unit. We rarely
encounter the issue, while it should be applied to stable releases, since
it fixes inappropriate API usage.

Thx for your efforts on this, much appreciated. It seems more than just
one or two users are hitting this crash and a fix despite all your
tremendous efforts it not yet in sight. Hence please allow me to ask:
would it cause a significant regression for users of 6.5 and later, if
we'd temporarily revert the culprit and anything depending on it until
this is solved? Because if not I wonder if we should go down that route,
even if it's a drastic measure; but then Greg could fix this in soon in
6.6.y as well.

Ciao, Thorsten
