usb: mtu3: simplify mtu3_req_complete()
Use argument req directly instead of mreq->request, they are the same usb request. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Link: https://lore.kernel.org/r/1595834101-13094-11-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
