In nd_dax_probe(), nd_dax_alloc() may fail and return NULL.
Check for NULL before attempting to
use nd_dax to avoid a NULL pointer dereference.

Avoid the use of 'we'.

In nd_dax_probe(), 'nd_dax' is allocated by nd_dax_alloc().
nd_dax_alloc() may fail and return NULL, so we should better check
it's return value to avoid a NULL pointer dereference
a bit later in the code.
