Subject: [PATCH v2 8/8] usb: dwc3: Check MISSED ISOC bit only for ISOC endpoints
Date: Fri, 17 Aug 2018 17:54:55 +0530 [thread overview]
Message-ID: <1534508695-12642-9-git-send-email-anurag.kumar.vulisha@xilinx.com> (raw)
In-Reply-To: <1534508695-12642-1-git-send-email-anurag.kumar.vulisha@xilinx.com>
When streaming is enabled on BULK endpoints and LST bit is set
observed MISSED ISOC bit set in event->status for BULK ep. Since
this bit is only valid for isocronous endpoints, changed the code
to check for isocrnous endpoints when MISSED ISOC bit is set.
