HID: alps: fix error return code in alps_input_configured()
When input_register_device() fails, no error return code is assigned. To fix this bug, ret is assigned with -ENOENT as error return code. Reported-by: TOTE Robot <oslab@tsinghua.edu.cn> Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
