Subject: [PATCH AUTOSEL 5.11 03/23] HID: alps: fix error return code in alps_input_configured()
Date: Mon, 19 Apr 2021 16:43:22 -0400 [thread overview]
Message-ID: <20210419204343.6134-3-sashal@kernel.org> (raw)
In-Reply-To: <20210419204343.6134-1-sashal@kernel.org>
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.
