Subject: [PATCH v2 1/3] edac: Fix error return code when edac_pci_add_device() fails
Date: Mon, 31 May 2021 22:53:00 +0800	[thread overview]
Message-ID: <20210531145302.9655-2-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210531145302.9655-1-thunder.leizhen@huawei.com>

When edac_pci_add_device() fails, fix to return -ENODEV from the error
handling case instead of 0.

The "goto err" in octeon_pci_probe() is removed to simplify code.
