Subject: [PATCH AUTOSEL 5.10 04/13] cavium: Return negative value when pci_alloc_irq_vectors() fails
Date: Mon, 25 Oct 2021 13:00:13 -0400 [thread overview]
Message-ID: <20211025170023.1394358-4-sashal@kernel.org> (raw)
In-Reply-To: <20211025170023.1394358-1-sashal@kernel.org>
From: Zheyu Ma <zheyuma97@gmail.com>
[ Upstream commit b2cddb44bddc1a9c5949a978bb454bba863264db ]
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
