From f9c56cdd3905c96c600456203637bd7ec8ec6383 Mon Sep 17 00:00:00 2001 From: Ido Shayevitz Date: Wed, 8 Feb 2012 13:56:48 +0200 Subject: [PATCH] usb: gadget: Clear usb_endpoint_descriptor inside the struct usb_ep on disable This fix a bug in f_serial, which expect the ep->desc to be NULL after disabling an endpoint.
