[PATCH 5.14 0/2] s390/pci: fix zpci_zdev_put() on reserve

[Niklas Schnelle <schnelle@xxxxxxxxxxxxx>]

Hi Greg, Hi Sasha,

Please take this backport of the upstream commit a46044a92add ("s390/pci: fix
zpci_zdev_put() on reserve") for the v5.14 stable series. After adding the
prerequisite commit 023cc3cb1e4b ("s390/pci: cleanup resources only if
necessary") both it and the original upstream patch apply cleanly. I have also
tested them with the original problem situation on top of v5.14.14 and
confirmed the issue to be fixed.

Thanks,
Niklas
