Do you think the original commit "4ec656bdf43a" of the file skx_edac.c (though it was removed) is the right commit to be used as the Fixes tag for this patch?
Fixes: 4ec656bdf43a ("EDAC, skx_edac: Add EDAC driver for Skylake")
This is the correct tag (this problem goes all the way back to the very first version of this driver).
