Subject: [PATCH 4.4 17/22] usb: dwc3: gadget: Set maxpacket size for ep0 IN
Date: Mon, 26 Feb 2018 21:16:17 +0100 [thread overview]
Message-ID: <20180226201559.477409900@linuxfoundation.org> (raw)
In-Reply-To: <20180226201558.681421374@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>
commit 6180026341e852a250e1f97ebdcf71684a3c81b9 upstream.
There are 2 control endpoint structures for DWC3. However, the driver
only updates the OUT direction control endpoint structure during
ConnectDone event. DWC3 driver needs to update the endpoint max packet
size for control IN endpoint as well. If the max packet size is not
properly set, then the driver will incorrectly calculate the data
transfer size and fail to send ZLP for HS/FS 3-stage control read
transfer.
The fix is simply to update the max packet size for the ep0 IN direction
during ConnectDone event.
