Date: Wed, 15 Jan 2014 13:50:21 -0800 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Michael Grzeschik <m.grzeschik@...gutronix.de>, Felipe Balbi <balbi@...com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 007/166] usb: gadget: composite: reset delayed_status on reset_config 3.8.13.16 -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.
