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

146 | multiple partitions). The dev_node_t structures need to be kept | |
147 | in a linked list starting at the 'dev' field of a dev_link_t | |
148 | structure. We allocate them in the card's private data structure, | |
149 | because they generally shouldn't be allocated dynamically. | |
