Subject: [PATCH AUTOSEL 5.14 13/18] cavium: Fix return values of the probe function
Date: Mon, 25 Oct 2021 12:59:26 -0400	[thread overview]
Message-ID: <20211025165939.1393655-13-sashal@kernel.org> (raw)
In-Reply-To: <20211025165939.1393655-1-sashal@kernel.org>

From: Zheyu Ma <zheyuma97@gmail.com>

[ Upstream commit c69b2f46876825c726bd8a97c7fa852d8932bc32 ]

During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
