Subject: usb: dwc3: gadget: fix ISOC TRB type on unaligned transfers
Date: Fri, 3 Aug 2018 10:53:55 +0300 [thread overview]
Message-ID: <20180803075355.20874-1-felipe.balbi@linux.intel.com> (raw)
When chaining ISOC TRBs together, only the first ISOC TRB should be of
type ISOC_FIRST, all others should be of type ISOC. This patch fixes
that.
Fixes: c6267a51639b ("usb: dwc3: gadget: align transfers to wMaxPacketSize")
Cc: <stable@vger.kernel.org> # v4.11+
