Subject: EDAC/igen6: Return the correct error type when not the MC owner
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f5e32344d472f1021b9d382333f01b356bc8b8b8;p=users%2Fjedix%2Flinux-maple.git

EDAC/igen6: Return the correct error type when not the MC owner

Return -EBUSY instead of -ENODEV just like the other EDAC drivers do.
