112 | A driver needs to provide a dev_node_t structure for each device |

114 | example, ethernet cards, modems). In other cases, there may be | |
115 | many actual or logical devices (SCSI adapters, memory cards with | |
116 | multiple partitions). The dev_node_t structures need to be kept | |
117 | in a linked list starting at the 'dev' field of a dev_link_t | |
118 | structure. We allocate them in the card's private data structure, | |
119 | because they generally shouldn't be allocated dynamically. | |
120 | ||
121 | In this case, we also provide a flag to indicate if a device is | |
122 | "stopped" due to a power management event, or card ejection. The | |
