Subject: [PATCH v2 6/8] usb: dwc3: check for requests in started list for stream capable endpoints
Date: Fri, 17 Aug 2018 17:54:53 +0530 [thread overview]
Message-ID: <1534508695-12642-7-git-send-email-anurag.kumar.vulisha@xilinx.com> (raw)
In-Reply-To: <1534508695-12642-1-git-send-email-anurag.kumar.vulisha@xilinx.com>
For stream capable endpoints, uas layer can queue mulpile requests on
single ep with different stream ids. So, there can be multiple pending
requests waiting to be transferred. This patch changes the code to check
for any pending requests waiting to be transferred on ep started_list and
calls __dwc3_gadget_kick_transfer() if any.
