This patch adds support for all input devices. It also provides the "device" and "driver" symlink for all USB HID devices. Other input drivers should also provide this information if they can (but that can be added later.) --- 25-akpm/drivers/input/evdev.c | 4 ++++ 25-akpm/drivers/input/input.c | 8 +++----- 25-akpm/drivers/input/joydev.c | 4 ++++ 25-akpm/drivers/input/mousedev.c | 8 +++++++- 25-akpm/drivers/input/tsdev.c | 4 ++++ 25-akpm/include/linux/input.h | 3 ++- 6 files changed, 24 insertions(+), 7 deletions(-) diff -puN drivers/input/evdev.c~sysfs-class-02-input drivers/input/evdev.c --- 25/drivers/input/evdev.c~sysfs-class-02-input Thu Jan 15 16:39:36 2004 +++ 25-akpm/drivers/input/evdev.c Thu Jan 15 16:39:36 2004 @@ -92,6 +92,7 @@ static int evdev_flush(struct file * fil static void evdev_free(struct evdev *evdev) { devfs_remove("input/event%d", evdev->minor);
