From 6819e3233f244be6e8ea4aba139434ada0698743 Mon Sep 17 00:00:00 2001 From: Jerry Zhang Date: Fri, 30 Mar 2018 15:32:19 -0700 Subject: [PATCH] usb: gadget: f_fs: Add compat_ioctl to epfiles MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows 32 bit owners of ffs endpoints to make ioctls into a 64 bit kernel. All of the current epfile ioctls can be handled with the same struct definitions as regular ioctl.
