From 3cf0ad02e42a91e85ffe9bd67422dd266531d3ec Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 25 Jan 2012 11:51:19 +0100 Subject: usb: gadget: dummy_hcd: don't assign ->desc on error case If the stream check fails then we leave ep->desc assigend but we return with an error code. The caller assumes the endpoint is not enabled (which is the case) but it can not enable it again due to this assigment.
