I'd be all in favor of that, but what Vaibhav is working toward is
eliminating use of legacy PM in PCI drivers.  I think unifying drivers
is really out of scope for that project.

If you'd rather leave gpio-ml-ioh.c alone for now, I suggest that
Vaibhav move on to other PCI drivers that use legacy PM.  If we
convert all the others away from legacy PM and gpio-ml-ioh.c is the
only one remaining, then I guess we can revisit this :)

Or, maybe converting gpio-ml-ioh.c now, along the lines of
226e6b866d74 ("gpio: pch: Convert to dev_pm_ops"), would be one small
step towards the eventual unification, by making gpio-pch and
gpio-ml-ioh a little more similar.
