pcmcia: dev_node removal (drivers with updated printk call)
As a second step, remove any usage of dev_node_t from drivers which only wrote to this typedef/struct, except one printk() which can easily be replaced by a dev_info()/dev_warn() call.

65 A linked list of "instances" of the skeleton device. Each actual
66 PCMCIA card corresponds to one device instance, and is described
67 by one struct pcmcia_device structure (defined in ds.h).
68
69 You may not want to use a linked list for this -- for example, the
70 memory card driver uses an array of struct pcmcia_device pointers, where minor
71 device numbers are used to derive the corresponding array index.

75 A driver needs to provide a dev_node_t structure for each device
76 on a card. In some cases, there is only one device per card (for
77 example, ethernet cards, modems). In other cases, there may be
78 many actual or logical devices (SCSI adapters, memory cards with
79 multiple partitions). The dev_node_t structures need to be kept
80 in a linked list starting at the 'dev' field of a struct pcmcia_device
81 structure. We allocate them in the card's private data structure,
82 because they generally can't be allocated dynamically.
