Suspend scenario in case of ohci-da8xx glue was not
properly handled as it was not suspending generic part
of ohci controller. Calling explicitly the ohci_suspend()
routine in ohci_da8xx_suspend() will ensure proper
handling of suspend scenario.

V2:
  -Incase ohci_suspend() fails, return right away without
   executing further.

V3:
  -Aligned variable "do_wakeup" and "ret".
  -pdev->dev.power.power_state stuff has been removed.

V4:
  -Properly aligned "do_wakeup" and "ret" variable.

Could you align this line more, so that it starts under the character after ( in the previous line.

  {
-	struct usb_hcd	*hcd	= platform_get_drvdata(dev);
+	struct usb_hcd	*hcd	= platform_get_drvdata(pdev);
  	struct ohci_hcd	*ohci	= hcd_to_ohci(hcd);
+	bool	do_wakeup	= device_may_wakeup(&pdev->dev);
+	int	ret;

   I wouldn't call this "properly aligned". It need one more tab.

WBR, Sergei
