- A driver needs to provide a dev_node_t structure for each device
- on a card. In some cases, there is only one device per card (for
- example, ethernet cards, modems). In other cases, there may be
- many actual or logical devices (SCSI adapters, memory cards with
- multiple partitions). The dev_node_t structures need to be kept
- in a linked list starting at the 'dev' field of a struct pcmcia_device
- structure. We allocate them in the card's private data structure,
- because they generally shouldn't be allocated dynamically.
-
- In this case, we also provide a flag to indicate if a device is
- "stopped" due to a power management event, or card ejection. The
- device IO routines can use a flag like this to throttle IO to a
- card that is not ready to accept it.
