[PATCH 0/4] PCI: endpoint: Doorbell-related fixes

[Koichiro Den]

Hi,

This is a small fix-only series related to the previous (v6)
doorbell-related series:
https://lore.kernel.org/linux-pci/20260209125316.2132589-1-den@xxxxxxxxxxxxx/

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

  1/4 fixes IRQ unwind in MSI doorbell setup (pci-epf-vntb)
  2/4 adds a bounds check for doorbell BAR offset (pci-epf-test)
  3/4 avoids free_irq() if doorbell IRQ was not successfully requested
      (pci-epf-test)
  4/4 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
