[PATCH] usb: ohci-at91: Fix the unhandle interrupt when resume

From: Guiting Shen
Date: Wed Jun 21 2023 - 22:57:56 EST


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.

Set the ohci->rh_state to OHCI_RH_SUSPEND instead of OHCI_RH_HALTED when
suspend to fix it.
