This failure:

$ zcat config.gz | grep DCDBAS
CONFIG_DCDBAS=m            <----------

$ zcat config.gz | grep SMBIOS
CONFIG_DELL_SMBIOS=y       <----------
ddCONFIG_DELL_SMBIOS_WMI=y
CONFIG_DELL_SMBIOS_SMM=y   <----------

Is no longer possible as of:

cc69c88 platform/x86: dell-smbios: Resolve dependency error on DCDBAS

+#
+# If the DELL_SMBIOS_SMM feature is enabled, the DELL_SMBIOS driver
+# becomes dependent on the DCDBAS driver. The "depends" line prevents a
+# configuration where DELL_SMBIOS=y while DCDBAS=m.
+#
 config DELL_SMBIOS
        tristate "Dell SMBIOS driver"
+       depends on DCDBAS || DCDBAS=n
