Without an EXPORT_SYMBOL_GPL this is not going to be very useful for
your driver.

Unless I am missing something here, the commit that made
'pci_enable_ptm()' private didn't remove the 'EXPORT_SYMBOL' from the
function definition in drivers/pci/pcie/ptm.c.

OOPS, indeed.  Looks like right now the function is nindeed exported,
but has no single user at all.
