Subject: [PATCH 08/17] usb: xhci-mtk: remove unnecessary members of mu3h_sch_tt struct
Date:   Fri, 5 Mar 2021 17:02:46 +0800
Message-ID: <1614934975-15188-8-git-send-email-chunfeng.yun@mediatek.com>

Precedence: bulk

The members @usb_tt and @tt_port in mu3h_sch_tt struct
are not used after initialization, so can be removed
