From 7125d584d20ba7624488ddefa84b17ea6ce558f1 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 19 Jul 2012 21:05:08 +0300 Subject: [PATCH] usb: dwc3: ep0: fix status phase delayed status direction commit 68d3e66 (usb: dwc3: ep0: fix for possible early delayed_status) added handling for early delayed status, but the current code only works because so far delayed status will always be on the IN direction. This patch makes the code more robust by making sure that we can handle all directions properly.
