+it's a version the driver can handle, that driver data structures can
+be allocated and initialized, and that any hardware can be initialized.
+Drivers often store a pointer to their state with dev_set_drvdata().
+When the driver has successfully bound itself to that device, then probe()
+returns zero and the driver model code will finish its part of binding

+/*
+ *      klist.c - Routines for manipulating klists.
+ *
+ *
+ *      This klist interface provides a couple of structures that wrap around 
+ *      struct list_head to provide explicit list "head" (struct klist) and 
+ *      list "node" (struct klist_node) objects. For struct klist, a spinlock
+ *      is included that protects access to the actual list itself. struct 
+ *      klist_node provides a pointer to the klist that owns it and a kref
+ *      reference count that indicates the number of current users of that node
+ *      in the list.
+ *
+ *      The entire point is to provide an interface for iterating over a list
+ *      that is safe and allows for modification of the list during the
+ *      iteration (e.g. insertion and removal), including modification of the
+ *      current node on the list.
+ *
+ *      It works using a 3rd object type - struct klist_iter - that is declared
+ *      and initialized before an iteration. klist_next() is used to acquire the
+ *      next element in the list. It returns NULL if there are no more items.
+ *      Internally, that routine takes the klist's lock, decrements the reference
+ *      count of the previous klist_node and increments the count of the next
+ *      klist_node. It then drops the lock and returns.
+ *
+ *      There are primitives for adding and removing nodes to/from a klist. 
+ *      When deleting, klist_del() will simply decrement the reference count. 
+ *      Only when the count goes to 0 is the node removed from the list. 
+ *      klist_remove() will try to delete the node from the list and block
+ *      until it is actually removed. This is useful for objects (like devices)
+ *      that have been removed from the system and must be freed (but must wait
+ *      until all accessors have finished).
