Sparse complains:

CHECK drivers/pci/controller/dwc/pcie-designware-debugfs.c
drivers/pci/controller/dwc/pcie-designware-debugfs.c:868:27: warning: symbol 'dw_pcie_ptm_ops' was not declared. Should it be static?

I should have noticed this earlier, sorry. As of v6.16-rc1, this is
now 852a1fdd34a8 ("PCI: dwc: Add debugfs support for PTM context")
upstream.
