Subject: [PATCH 4.14 08/25] ata: sata_mv: Fix the error handling of mv_chip_id()
Date: Mon, 1 Nov 2021 10:17:20 +0100 [thread overview]
Message-ID: <20211101082448.996722973@linuxfoundation.org> (raw)
In-Reply-To: <20211101082447.070493993@linuxfoundation.org>
From: Zheyu Ma <zheyuma97@gmail.com>
commit a0023bb9dd9bc439d44604eeec62426a990054cd upstream.
mv_init_host() propagates the value returned by mv_chip_id() which in turn
gets propagated by mv_pci_init_one() and hits local_pci_probe().
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
Since this is a bug rather than a recoverable runtime error we should
use dev_alert() instead of dev_err().
