Subject: [PATCH 5.10 19/26] usb: gadget: tegra-xudc: fix the wrong mult value for HS isoc or intr
Date: Fri, 10 Sep 2021 14:30:23 +0200 [thread overview]
Message-ID: <20210910122916.875884800@linuxfoundation.org> (raw)
In-Reply-To: <20210910122916.253646001@linuxfoundation.org>
From: Chunfeng Yun <chunfeng.yun@mediatek.com>
commit eeb0cfb6b2b6b731902e68af641e30bd31be3c7b upstream.
usb_endpoint_maxp() only returns the bit[10:0] of wMaxPacketSize
of endpoint descriptor, not includes bit[12:11] anymore, so use
usb_endpoint_maxp_mult() instead.
Meanwhile no need AND 0x7ff when get maxp, remove it.
Fixes: 49db427232fe ("usb: gadget: Add UDC driver for tegra XUSB device mode controller")
