Subject: [PATCH v2 0/2] s390/pci: Fix missing pci_dev_put() in zpci_report_status()
Date: Wed, 19 Aug 2026 11:58:29 +0200	[thread overview]
Message-ID: <20260819-fix_zpci_report_status_pdev_leak-v2-0-da0c4aa7c0ca@linux.ibm.com> (raw)

Hi All,

This series fixes two issues found in zpci_report_status() by
LLM review. A missing pci_dev_put() which could prevent proper removal
on hot unplug and a too short device lock critical section.

Thanks,
Niklas
