From 3dda4e373c7474cfe280f4270b70c1563f92a2a7 Mon Sep 17 00:00:00 2001 From: Hansjoerg Lipp Date: Sat, 22 Apr 2006 18:43:00 +0200 Subject: [PATCH] i4l gigaset: move sysfs entry to tty class device Using the class device pointer returned by tty_register_device() with part 1 of the patch, attach the Gigaset drivers' "cidmode" sysfs entry to its tty class device, where it can be found more easily by users who do not know nor care which USB port the device is attached to.
