125 | A dev_link_t structure has fields for most things that are needed | |

128 | 'priv' pointer in a dev_link_t structure can be used to point to | |
129 | a device-specific private data structure, like this. | |
130 | ||
131 | A driver needs to provide a dev_node_t structure for each device | |
132 | on a card. In some cases, there is only one device per card (for | |
133 | example, ethernet cards, modems). In other cases, there may be | |
134 | many actual or logical devices (SCSI adapters, memory cards with | |
135 | multiple partitions). The dev_node_t structures need to be kept | |
136 | in a linked list starting at the 'dev' field of a dev_link_t | |
137 | structure. We allocate them in the card's private data structure, | |
138 | because they generally shouldn't be allocated dynamically. | |
139 | ||
140 | In this case, we also provide a flag to indicate if a device is | |
141 | "stopped" due to a power management event, or card ejection. The | |
