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

113 | example, ethernet cards, modems). In other cases, there may be | |
114 | many actual or logical devices (SCSI adapters, memory cards with | |
115 | multiple partitions). The dev_node_t structures need to be kept | |
fba395ee | 116 | in a linked list starting at the 'dev' field of a struct pcmcia_device |

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