[PATCH v9 7/7] EDAC/igen6: Return consistent errno when another edac driver is enabled

From: Jia He
Date: Mon Oct 17 2022 - 09:03:30 EST


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.
