From e21de10cd8b1338200d96038aa66fb966fcf6ed0 Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Sun, 10 Mar 2013 02:49:14 +0200 Subject: usb: musb: gadget: clear gadget_driver when gadget is stopped Some musb glue drivers use gadget_driver pointer to know if any gadget drivers are loaded at some moment and base further decisions on it, like to do runtime suspend/resume or not. Right now the pointer is left alone on stop and OMAP musb glue later does wrong runtime_pm decisions because of it. Clear the gadget_driver pointer on remove, it's invalid after stop anyway.
