[PATCH v3 0/4] s390/pci: Fix some zpci_report_status() issues

[Niklas Schnelle <schnelle@linux.ibm.com>]

Hi All,

This series fixes four issues found in zpci_report_status().

* A missing pci_dev_put() (patch 1)
* Dropping the device lock too early (patch 2)
* Missing an error report when there is no associated pdev (patch 3)
* An inconsistent error report when skipping recovery on permanent
  failure (patch 4)

Thanks,
Niklas

Changes in v3:
- Change in approach, pass the pdev as a parameter
- Add a device lock assertion and extract a helper function for pdev
  specific status
- Also report the status if no pdev is associated
- Fix an inconsistent report when recovery is skipped due to permanent
  failure
- Link to v2: https://lore.kernel.org/r/20260819-fix_zpci_report_status_pdev_leak-v2-0-da0c4aa7c0ca@linux.ibm.com

Changes in v2:
- Added a second fix to address Sashiko's finding of having
  to hold the device lock during the call to zpci_report_status()
- Add R-bs from Matthew and Farhan
- Link to v1: https://lore.kernel.org/r/20260818-fix_zpci_report_status_pdev_leak-v1-1-576520f4d068@linux.ibm.com
