6.13-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 1db806ec06b7c6e08e8af57088da067963ddf117 ]
After 17423360a27a ("PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"), pci_save_aspm_l1ss_state(dev) saves the L1SS state for "dev", and pci_restore_aspm_l1ss_state(dev) restores the state for both "dev" and its parent.
[...]
Please withhold this commit from stable until its fix ("PCI/ASPM: Fix L1SS saving") can be pushed at the same as having this commit alone can causes PCIe devices to becomes unavailable and hang the system during PM transitions.
The fix is currently in pci/for-linus as the commit c312f005dedc, but Bjorn might add more reported-by/tested-by tags if more people hit it before the commit makes into Linus' tree so don't expect that commit id to be stable just yet.
Ok, now dropped from all stable queues, thanks for letting us know.
Any chance these can be re-included? That's:
1db806ec06b7 ("PCI/ASPM: Save parent L1SS config in pci_save_aspm_l1ss_state()") 7507eb3e7bfa ("PCI/ASPM: Fix L1SS saving")
We've independently backported them into kernels we're using, but it seems wise to get 6.12.y, etc., back up to date.
Now queued up, thanks.
