Suspend scenario in case of ohci-omap glue was not properly handled as it was not suspending generic part of ohci controller. Calling explicitly the ohci_suspend() routine in ohci_omap_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".
V4: -The do_wakeup and ret variable alignment is removed. --- drivers/usb/host/ohci-omap.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-)
