Subject: [PATCH 5.13 13/22] usb: cdnsp: fix the wrong mult value for HS isoc or intr
Date: Fri, 10 Sep 2021 14:30:12 +0200 [thread overview]
Message-ID: <20210910122916.365208009@linuxfoundation.org> (raw)
In-Reply-To: <20210910122915.942645251@linuxfoundation.org>
From: Chunfeng Yun <chunfeng.yun@mediatek.com>
commit e9ab75f26eb9354dfc03aea3401b8cfb42cd6718 upstream.
usb_endpoint_maxp() only returns the bit[10:0] of wMaxPacketSize
of endpoint descriptor, not include bit[12:11] anymore, so use
usb_endpoint_maxp_mult() instead.
Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver")
