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@valinux.co.jp/
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.
v1: https://lore.kernel.org/linux-pci/20260215150914.3392479-1-den@valinux.co.jp/
