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. Impact: some error return codes changed Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
