Running 'ut dm' on the sandbox without -D or -d results in segmentation faults due to NULL pointer dereferences. Check that device pointers are non-NULL before using them. Use ut_assertnonnull() for pointers instead of ut_assert(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Tested-by: Philippe Reynes <philippe.reynes@softathome.com>
