Subject: [PATCH v6 8/8] EDAC/igen6: Return consistent errno when another edac driver is enabled
Date: Mon, 12 Sep 2022 14:40:05 +0000 [thread overview]
Message-ID: <20220912144005.212624-9-justin.he@arm.com> (raw)
In-Reply-To: <20220912144005.212624-1-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.
