Subject: [PATCH 2/5] usb: mtu3: remove repeated setting of speed
Date: Fri, 28 May 2021 14:10:57 +0800 [thread overview]
Message-ID: <1622182260-23767-2-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1622182260-23767-1-git-send-email-chunfeng.yun@mediatek.com>
mtu3_gadget_start() will set speed, no need set it again in
mtu3_gadget_set_speed(), just save the desired speed.
