Subject: [PATCH V6 04/10] usb: dwc3: update stream id in depcmd
Date: Sat, 13 Oct 2018 18:44:51 +0530	[thread overview]
Message-ID: <1539436498-24892-5-git-send-email-anurag.kumar.vulisha@xilinx.com> (raw)
In-Reply-To: <1539436498-24892-1-git-send-email-anurag.kumar.vulisha@xilinx.com>

For stream capable endpoints, stream id related information
needs to be updated into DEPCMD while issuing START TRANSFER.
This patch does the same.
