dev_node_t was only used to transport some minor/major numbers from the PCMCIA device drivers to deprecated userspace helpers. However, only a few drivers made use of it, and the userspace helpers are deprecated anyways. Therefore, get rid of dev_node_t . As a first step, remove any usage of dev_node_t from drivers which only wrote to this typedef/struct, but did not make use of it.
