Subject: [PATCH v2 08/18] usb: xhci-mtk: remove unnecessary members of mu3h_sch_tt struct
Date: Mon, 8 Mar 2021 10:51:57 +0800	[thread overview]
Message-ID: <9afecc2411895a3c76658df26ebca1c961a39fbb.1615170625.git.chunfeng.yun@mediatek.com> (raw)

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