* Slot states for PIOCGSTATE
*
* Here's a state diagram of all the possible states:
*
* power x 1
* -------------------
* / \
* / v
* resume +----------+ power x 0 +----------+
* ------->| inactive |<--------------| filled |
* / +----------+ +----------+
* / / \ ^ |
* nil <--------- \ insert or | | suspend or
* suspend \ power x 1 | | eject
* \ | v
* \ +----------+
* ----------->| empty |
* eject +----------+
*
* Note, the above diagram is for the state. On suspend, the laststate
* gets set to suspend to tell pccardd what happened. Also the nil state
* means that when the no state change has happened. Note: if you eject
* while suspended in the inactive state, you will return to the
* empty state if you do not insert a new card and to the inactive state
* if you do insert a new card.
*
* Some might argue that inactive should be sticky forever and
* eject/insert shouldn't take it out of that state. They might be
* right. On the other hand, some would argue that eject resets all
* state. They might be right. They both can't be right. The above
* represents a reasonable compromise between the two.
*
* Some bridges allow one to query to see if the card was changed while
* we were suspended. Others do not. We make no use of this functionality
* at this time.
