Message-Id: <20131218210523.168723468@linuxfoundation.org> Date: Wed, 18 Dec 2013 13:08:21 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Michael Grzeschik <m.grzeschik@...gutronix.de>, Felipe Balbi <balbi@...com> Subject: [PATCH 3.4 13/31] usb: gadget: composite: reset delayed_status on reset_config 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael Grzeschik <m.grzeschik@...gutronix.de> 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.
