Subject: [PATCH v2 7/7] EDAC/igen6: Keep returned errno consistent when edac mc has been enabled
Date: Wed, 17 Aug 2022 14:34:58 +0000 [thread overview]
Message-ID: <20220817143458.335938-8-justin.he@arm.com> (raw)
In-Reply-To: <20220817143458.335938-1-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.
