From: Manjunath Goudar <[email protected]> Suspend scenario in case of ohci-pxa27x glue was not properly handled as it was not suspending generic part of ohci controller. Alan Stern suggested, properly handle ohci-pxa27x suspend scenario.
Calling explicitly the ohci_suspend() routine in ohci_hcd_pxa27x_drv_suspend() will ensure proper handling of suspend scenario.
