OK. Then do you mean the following? :)
If I am wrong, please let me know.
Thank you.
#ifdef CONFIG_PM_SLEEP
static int dwc3_pci_suspend(struct device *dev)
{
struct pci_dev *pci = to_pci_dev(dev);
pci_disable_device(pci);
return 0;
}
static int dwc3_pci_resume(struct device *dev)
{
struct pci_dev *pci = to_pci_dev(dev);
int ret;
ret = pci_enable_device(pci);
if (ret) {
dev_err(dev, "can't re-enable device --> %d\n", ret);
return ret;
}
pci_set_master(pci);
return 0;
}
#endif /* CONFIG_PM_SLEEP */
static const struct dev_pm_ops dwc3_pci_dev_pm_ops = {
SET_SYSTEM_SLEEP_PM_OPS(dwc3_pci_suspend, dwc3_pci_resume)
};
