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

115 | many actual or logical devices (SCSI adapters, memory cards with | |
116 | multiple partitions). The dev_node_t structures need to be kept | |
fba395ee | 117 | in a linked list starting at the 'dev' field of a struct pcmcia_device |

118 | structure. We allocate them in the card's private data structure, |
119 | because they generally shouldn't be allocated dynamically. | |

122 | "stopped" due to a power management event, or card ejection. The | |
