Subject: [PATCH v2 1/5] usb: dwc2: gadget: use ep->fifo_index in context of FIFO registers
Date: Wed, 03 Feb 2016 12:36:30 +0100 [thread overview]
Message-ID: <1454499394-4610-2-git-send-email-r.baldyga@samsung.com> (raw)
In-Reply-To: <1454499394-4610-1-git-send-email-r.baldyga@samsung.com>
In context of FIFO registers we use ep->fifo_index instead of ep->index.
