Subject: [PATCH v2 10/18] usb: xhci-mtk: add a member @speed in mu3h_sch_ep_info struct
Date: Mon, 8 Mar 2021 10:51:59 +0800 [thread overview]
Message-ID: <cda0833e44d6027cc8fdee1e29ce2b5b2a6ac03d.1615170625.git.chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <d287899e6beb2fc1bfb8900c75a872f628ecde55.1615170625.git.chunfeng.yun@mediatek.com>
This is used to drop parameter @udev for some functions,
meanwhile remove some unused @udev parameter.
