From 3f612132c7164d5cc9ed677a2fdf8950222d2170 Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Sun, 8 Mar 2009 05:23:13 +0000 Subject: [PATCH] gigaset: return -ENOTTY for unimplemented functions A number of functions in the usb_gigaset module will return -EINVAL if CONFIG_GIGASET_UNDOCREQ is not set. Make these return -ENOTTY as it's more specific and it might make it easier to see (from userspace) why these functions actually fail.
