From 4470dc52a72c1e8c06546f923f6a817cff4a34a7 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Mon, 11 Nov 2013 23:43:32 +0100 Subject: [PATCH] usb: gadget: composite: reset delayed_status on reset_config commit 2bac51a1827a18821150ed8c9f9752c02f9c2b02 upstream. The delayed_status value is used to keep track of status response packets on ep0. It needs to be reset or the set_config function would still delay the answer, if the usb device got unplugged while waiting for setup_continue to be called.
