H A Ddm-linear.cdiff 976431b02c2ef92ae3f8b6a7d699fc554025e118 Fri Mar 30 02:22:13 CEST 2018 Dan Williams <dan.j.williams@intel.com> dax, dm: allow device-mapper to operate without dax support

Change device-mapper's DAX dependency to require the presence of at
least one DAX_DRIVER. This allows device-mapper to be built without
bringing the DAX core along which is especially wasteful when there are
no DAX drivers, like BLK_DEV_PMEM, configured.
