Pull firewire fix from Takashi Sakamoto:
"A fix to suppress a warning about unreleased IRQ for 1394 OHCI
hardware when disabling MSI.
In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was
optimized into the managed device resources. Edmund Raile points out
that the change brings the warning about unreleased IRQ at the call of
pci_disable_msi(), since the API expects that the relevant IRQ has
already been released in advance.
As long as the API is called in .remove callback of PCI device
operation, it is prohibited to maintain the IRQ as the part of managed
device resource. As a workaround, the IRQ is explicitly released at
.remove callback, before the call of pci_disable_msi().
pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I
have a plan to replace it with the modern API in the development for
the future version of Linux kernel. So at present I keep them as is"
