Merge tag 'pci-v6.9-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci fixes from Bjorn Helgaas:
- Update kernel-parameters doc to describe "pcie_aspm=off" more
accurately (Bjorn Helgaas)
- Restore the parent's (not the child's) ASPM state to the parent
during resume, which fixes a reboot during resume (Kai-Heng Feng)
* tag 'pci-v6.9-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci:
PCI/ASPM: Restore parent state to parent, child state to child
PCI/ASPM: Clarify that pcie_aspm=off means leave ASPM untouched
