Subject: [PATCH v3 7/7] usb: gadget: remove unnecessary AND operation when get ep maxp
Date: Fri, 13 Aug 2021 14:30:53 +0800	[thread overview]
Message-ID: <1628836253-7432-7-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1628836253-7432-1-git-send-email-chunfeng.yun@mediatek.com>

usb_endpoint_maxp() already returns actual max packet size, no need
to AND 0x7ff.
