From 28c5980b5494b8163d6cba5a5007b6ec7e63de66 Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Fri, 13 Jun 2014 15:38:04 +0200 Subject: [PATCH] usb: gadget: f_fs: resurect usb_functionfs_descs_head structure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 09122141785348bf9539762a5f5dbbae3761c783 upstream. Even though usb_functionfs_descs_head structure is now deprecated, it has been used by some user space tools. Its removel in commit [ac8dde1: “Add flags to descriptors block”] was an oversight leading to build breakage for such tools. Bring it back so that old user space tools can still be build without problems on newer kernel versions.
