I am glad the problem is fixed. But I am puzzled. pnp_bus_resume()

don't see where how restore is handled prior to this change.
Take a look at drivers/base/platform.c::platform_pm_restore()
Thanks.
Yes I see it now. Before the conversion, platform_legacy_resume() path
is taken since pnp didn't have pm.
if (drv->pm) {
if (drv->pm->restore)
ret = drv->pm->restore(dev);
} else {
ret = platform_legacy_resume(dev);
}
Thanks for fixing the problem.
