Subject: [RESEND PATCH v2 10/11] usb: xhci: use macros with parameter to fill ep_info2
Date: Wed,  2 Sep 2020 08:13:42 +0200	[thread overview]
Message-ID: <20200902061343.3185-10-linux@fw-web.de> (raw)
In-Reply-To: <20200902061343.3185-1-linux@fw-web.de>

From: Chunfeng Yun <chunfeng.yun@mediatek.com>

Use macros with parameter to fill ep_info2, then some macros
for MASK and SHIFT can be removed
