[PATCH v2 0/3] PCI: endpoint: Doorbell-related fixes

Hi,

This is a small fix-only series related to the previous (v6)
doorbell-related series:
https://lore.kernel.org/linux-pci/[email protected]/

These patches address a few independent fixes in pci-epf-vntb,
pci-epf-test and pci-ep-msi:

  1/3 fixes IRQ unwind in MSI doorbell setup (pci-epf-vntb)
  2/3 avoids free_irq() if doorbell IRQ was not successfully requested
      (pci-epf-test)
  3/3 fixes error unwind and prevent double allocation in
      pci_epf_alloc_doorbell() (pci-ep-msi)

These fixes were originally intended to be included in the next revision
of the main series. However, doing so would have grown the v7 series to
around 15 patches, so I am posting them separately to keep the feature
series manageable.

Kind regards,
Koichiro

Changes in v2:
  - Removed a minor refactoring part from [PATCH 1/4], keeping the iterator type
    int, rather than changing it to unsigned int.
  - Dropped [PATCH 2/4] (bounds check). It's a theoretical future-proofing guard
    rather than a fix for today.
  - Dropped the db_irq_requested flag and instead moved free_irq() to the
    appropriate call sites.
