a device-specific private data structure, like this.

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 dev_link_t
|
|
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
