Would be nicer to use dev_to_node helper here, which already checks for 
CONFIG_NUMA

include/linux/device.h:
#ifdef CONFIG_NUMA
static inline int dev_to_node(struct device *dev)
{
         return dev->numa_node;
}
static inline void set_dev_node(struct device *dev, int node)
{
         dev->numa_node = node;
}
#else
static inline int dev_to_node(struct device *dev)
{
         return -1;
}
static inline void set_dev_node(struct device *dev, int node)
{
}
#endif
