Subject[PATCH] edac: fix skx_edac build error when ACPI_NFIT=m
From: Randy Dunlap <>

Prevent build error when CONFIG_ACPI_NFIT=m and CONFIG_EDAC_SKX=y
by limiting EDAC_SKX based on how ACPI_NFIT is set.

Fixes this build error:
drivers/edac/skx_edac.o: In function `get_nvdimm_info':
../drivers/edac/skx_edac.c:399: undefined reference to `nfit_get_smbios_id'

Fixes: 58ca9ac1463d ("EDAC, skx_edac: Detect non-volatile DIMMs")
