Subject: [PATCH v7 8/8] EDAC/igen6: Return consistent errno when another edac driver is enabled
Date: Thu, 29 Sep 2022 02:37:26 +0000 [thread overview]
Message-ID: <20220929023726.73727-9-justin.he@arm.com> (raw)
In-Reply-To: <20220929023726.73727-1-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.
