[REGRESSION P/N][PATCH 0/1] Fix regression to PCI pass-through in QEMU/KVM

[Stefan Bader]

BugLink: https://bugs.launchpad.net/bugs/2117494

[SRU Justification]

Impact: Reported regression to PCI pass-through in QEMU/KVM (https://lists.ubuntu.com/archives/kernel-team/2025-July/161565.html) which was caused by changes to fix suspend/resume on disks with BIOS password set (bug #2110090).

Fix: Upstream fix from 6.16-rc3 addressing the issue (see below)

Testcase: Requires to set up a VM with PCI pass-through.

Regression potential: Things related to PCI power management (devices not being initialized or not properly resuming after suspend).

Mario Limonciello (1):
  PCI/PM: Set up runtime PM even for devices without PCI PM
