Subject: [PATCH v4 0/6] Fix some issues related to an interrupt type in pci_endpoint_test

This series solves some issues about global "irq_type" that is used for
indicating the current type for users.

In addition, avoid an unexpected warning that occur due to interrupts
remaining after displaying an error caused by devm_request_irq().

Patch 1 includes adding GET_IRQTYPE test (check for failure).
Patch 2-4 include fixes for stable kernels that have global "irq_type".
Patch 5-6 include improvements for the latest.

Changes since v3:
- Add GET_IRQTYPE check to pci_endpoint test in selftests
- Add the reason why global variables aren't necessary (patch 5/6)
- Add Reviewed-by: lines (patch {2, 4, 6}/6)

Changes since v2:
- Rebase to v6.14-rc1
- Update message to clarify, and add result of call trace (patch 1/5)
- Add Reviewed-by: lines (patch 2/5)
- Add new patch to remove global "irq_type" variable (patch 4/5)
- Add new patch to replace "devm" version of IRQ functions (patch 5/5)

Changes since v1:
- Divide original patch into two
- Add an error message example
- Add "pcitest" display example
- Add a patch to fix an interrupt remaining issue

Kunihiko Hayashi (6):
  selftests: pci_endpoint: Add GET_IRQTYPE checks to each interrupt test
  misc: pci_endpoint_test: Avoid issue of interrupts remaining after
    request_irq error
  misc: pci_endpoint_test: Fix displaying irq_type after request_irq
    error
  misc: pci_endpoint_test: Fix irq_type to convey the correct type
  misc: pci_endpoint_test: Remove global 'irq_type' and 'no_msi'
  misc: pci_endpoint_test: Do not use managed irq functions
