[PATCH AUTOSEL 4.19 02/12] HID: alps: fix error return code in alps_input_configured()

[Sasha Levin]

From: Jia-Ju Bai <baijiaju1990@gmail.com>

[ Upstream commit fa8ba6e5dc0e78e409e503ddcfceef5dd96527f4 ]

When input_register_device() fails, no error return code is assigned.
To fix this bug, ret is assigned with -ENOENT as error return code.
