From c0ca324d09a041ab56be1aaeb5a7cc64c47f877b Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 4 Apr 2016 09:11:51 +0300 Subject: [PATCH] usb: dwc3: gadget: combine return points into a single one dwc3_send_gadget_ep_cmd() had three return points. That becomes a pain to track when we need to debug something or if we need to add more code before returning. Let's combine all three return points into a single one just by introducing a local 'ret' variable.
