Subjectkobj_to_dev ?

Hi Greg, could this be added to device.h:

--- 1.112/include/linux/device.h Wed Jan 7 23:58:16 2004

void (*release)(struct device * dev);
};

+#define kobj_to_dev(k) container_of((k), struct device, kobj)
+
static inline struct device *
list_to_dev(struct list_head *node)
{
I'm using it as the following (inspired by find_bus), and it seems like
it would make sense to put in device.h.

struct vio_dev *vio_find_device(const char *name)
{
struct kobject *kobj;
kobj = kset_find_obj(&vio_bus_type.devices, name);
if (!kobj)
return NULL;
return to_vio_dev(kobj_to_dev(kobj));
}
As a side node, since those #defines don't to type-checking, would it
make sense to name them with both types? E.g. "kobj_to_dev" instead of
just "to_dev"?
