Subject: [PATCH 1/2] usbip: Remove repeated setting of hcd->state in vhci_bus_suspend()
Date: Mon,  6 May 2019 21:55:49 +0900	[thread overview]
Message-ID: <20190506125550.7826-1-suwan.kim027@gmail.com> (raw)

When hcd suspends execution, hcd_bus_suspend() calls vhci_bus_suspend()
which sets hcd->state as HC_STATE_SUSPENDED. But after calling
vhci_bus_suspend(), hcd_bus_suspend() also sets hcd->state as
HC_STATE_SUSPENDED.
So, setting hcd->state in vhci_hcd_suspend() is unnecessary.
