Subject: [PATCH v10 7/7] EDAC/igen6: Return consistent errno when another edac driver is enabled
Date: Tue, 18 Oct 2022 08:22:14 +0000 [thread overview]
Message-ID: <20221018082214.569504-8-justin.he@arm.com> (raw)
In-Reply-To: <20221018082214.569504-1-justin.he@arm.com>
Only a single edac driver can be enabled for EDAC MC. The igen6_init()
should be returned with EBUSY instead of ENODEV, which is consistent with
other edac drivers.
