Subject: [PATCH v4 8/8] EDAC/igen6: Return consistent errno when another edac driver is enabled
Date: Wed, 31 Aug 2022 07:40:27 +0000 [thread overview]
Message-ID: <20220831074027.13849-9-justin.he@arm.com> (raw)
In-Reply-To: <20220831074027.13849-1-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.
