From 906dbadf304e859314dc2f96ebfb126f002c90cf Mon Sep 17 00:00:00 2001 From: Guido Kiener Date: Mon, 18 Mar 2019 09:18:34 +0100 Subject: usb: gadget: net2272: Fix net2272_dequeue() [ Upstream commit 091dacc3cc10979ab0422f0a9f7fcc27eee97e69 ] Restore the status of ep->stopped in function net2272_dequeue(). When the given request is not found in the endpoint queue the function returns -EINVAL without restoring the state of ep->stopped. Thus the endpoint keeps blocked and does not transfer any data anymore. This fix is only compile-tested, since we do not have a corresponding hardware. An analogous fix was tested in the sibling driver.
