Merge branch 'pci-fixes'

Tobias Schumacher says:

====================

Commit f770950a4709 ("s390/pci: Migrate s390 IRQ logic to IRQ
domain API") introduced several bugs in error handling and cleanup
paths. This series fixes these issues:

1. Double-free and NULL dereference in the parent MSI domain cleanup
2. Leak of a zpci_sbv summary bit when AIBV creation fails
3. Directed-mode teardown freeing zdev->max_msi bits instead of the
   zdev->msi_nr_irqs bits that were allocated
4. Use-after-free race between floating IRQ delivery and teardown

Patch 5 is unrelated to the migration. zpci_directed_irq_init() has
leaked its allocations on the -ENOMEM paths since it was added in
e979ce7bced2 ("s390/pci: provide support for CPU directed interrupts").

Patch 6 is a cleanup that removes an unnecessary update of
zpci_msi_parent_ops from the per-bus domain creation path.

Patch 7 is a cleanup that drops the unused index argument of
zpci_msi_clear_airq(). The doubled index it removes never selected a
wrong entry, so it is not a fix.

Patch 8 is a cleanup that unregisters the adapter interrupt first in
zpci_irq_exit().

Patches 1 to 5 carry Cc: stable. Patches 6 to 8 do not; none of them
changes behaviour.
