Subject: [PATCH] cavium: Fix return values of the probe function
Date: Mon, 18 Oct 2021 14:32:57 +0000 [thread overview]
Message-ID: <1634567577-4033-1-git-send-email-zheyuma97@gmail.com> (raw)
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
