IIRC, the standard way to do things like that is something like:
config HAVE_MESH_DRIVER
default n
config RANDOM_DRIVER
select HAVE_MESH_DRIVER
config MESH
default y if HAVE_MESH_DRIVER
That way it's default on if drivers are selected which have mesh
support but still user selectable (either to disable or if out-of-tree
drivers want it).
