Subject: [PATCH V6 10/10] usb: dwc3: Check MISSED ISOC bit only for ISOC endpoints
Date: Sat, 13 Oct 2018 18:44:58 +0530	[thread overview]
Message-ID: <1539436498-24892-12-git-send-email-anurag.kumar.vulisha@xilinx.com> (raw)
In-Reply-To: <1539436498-24892-1-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.
