Subject: [PATCH] usb: host: Initiate urb ep with udev ep0
Git-commit: 9013d8fc0ad91dc369f5b8ea708b9b068aa5d434
References: jsc#PED-531
Patch-mainline: v6.1-rc1
Currently we look up for endpoint in a table and initate urb endpoint
with it. This is unnecessary because the lookup will always result in
endpoint 0.
