Subject: [PATCH] hid: hid-alps: fix error return code in alps_input_configured()
Date: Thu, 4 Mar 2021 05:19:57 -0800 [thread overview]
Message-ID: <20210304131957.7089-1-baijiaju1990@gmail.com> (raw)
When input_register_device() fails, no error return code is assigned.
To fix this bug, ret is assigned with -ENOENT as error return code.
