Hi,
We have a bug report against our driver in compat that will affect
everyone else too. In
commit f60dc0138aa19769bf8bab9f93b043235428b66f
Author: John W. Linville <linville@xxxxxxxxxxxxx>

iwlwifi: Convert to new PCI PM framework
and the similar patches to other drivers all drivers were converted to
use .driver.pm suspend/resume callbacks, and that removed
pci_save_state(pdev);
pci_disable_device(pdev);
pci_set_power_state(pdev, PCI_D3hot);
on suspend and the corresponding calls on resume. The compat backport
never added them back but just re-wired the callbacks, so on older
kernels we don't call these functions at all any more, and that breaks
suspend/resume.
Anyone have ideas of how to handle it? Maybe with compat_pci_suspend(),
whatever that is? If it even needs to exist -- maybe we could redefine
SIMPLE_DEV_PM_OPS in compat instead or in addition?
