Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=66a622275a11fb070b4dae3926d3a1a5d9cbecda



--------------------------------

commit c55afcbe upstream.

The ohci_hcd_at91_drv_suspend() sets ohci->rh_state to OHCI_RH_HALTED when
suspend which will let the ohci_irq() skip the interrupt after resume. And
nobody to handle this interrupt.

According to the comment in ohci_hcd_at91_drv_suspend(), it need to reset
when resume from suspend(MEM) to fix by setting "hibernated" argument of
ohci_resume().
