From f135617224b4a1113b26b8ee5877e94f38e40d1e Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Fri, 10 Feb 2012 09:54:51 +0100 Subject: [PATCH] usb: gadget: rndis: fix Missing req->context assignment It is crucial to assign each req->context value to struct rndis. The problem happens for multi function gadget (g_multi) when multiple functions are calling common usb_composite_dev control request. It might happen that *_setup method from one usb function will alter some fields of this common request issued by other USB function.
