From 7cf7beffaf8135c8af989609075ed1221282fd14 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C5=81ukasz=20Majewski?= Date: Mon, 12 Mar 2012 22:08:06 +0000 Subject: [PATCH] usb:udc:samsung:fix Remove the req_config flag The dev->req_config flag was indicating that the forwarded request needs to perform the usb gadget delayed status. This is however not needed anymore, so it can be removed.
