[PATCH] pcmcia: remove dev_list from drivers
The linked list of devices managed by each PCMCIA driver is, in very most
cases, unused. Therefore, remove it from many drivers.

- A dev_link_t structure has fields for most things that are needed

- To simplify the data structure handling, we actually include the

A driver needs to provide a dev_node_t structure for each device
on a card. In some cases, there is only one device per card (for
example, ethernet cards, modems). In other cases, there may be
