  PCI/pwrctrl: Unregister platform device only if one actually exists (2024-11-30 11:41:25 -0600)

----------------------------------------------------------------
- When removing a PCI device, only look up and remove a platform device
  if there is an associated device node for which there could be a platform
  device, to fix a merge window regression (Brian Norris)

[GIT PULL] PCI fixes for v6.13

  PCI/bwctrl: Enable only if more than one speed is supported (2024-12-19 16:36:36 +0000)

----------------------------------------------------------------
PCI fixes for Linux 6.13

Two small patches that are important for fixing boot time hang on Intel JHL7540
"Titan Ridge" platforms equipped with a Thunderbolt controller.

The boot time issue manifests itself when a PCI Express bandwidth control is
unnecessarily enabled on the Thunderbolt controller downstream ports, which
only supports a link speed of 2.5 GT/s in accordance with USB4 v2 specification
(p. 671, sec. 11.2.1, "PCIe Physical Layer Logical Sub-block").

As such, there is no need to enable bandwidth control on such downstream port
links, which also works around the issue.

Both patches were tested by the original reporter on the hardware on which the
failure origin golly manifested itself. Both fixes were proven to resolve the
reported boot hang issue, and both patches have been in linux-next this week
with no reported problems.
