Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:

- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
  clean up automatically on calls to pcmcia_disable_device() or
  device ejection.

- drivers still not capable of IRQF_SHARED (or not telling us so) may
  use the deprecated pcmcia_request_exclusive_irq() for the time
  being; they might receive a shared IRQ nonetheless.

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.

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.

  To: linux-pcmcia; +Cc: netdev, linux-wireless, Dominik Brodowski

As a third step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, except to determine whether
register_netdev() succeeded previously. However, the function calling
unregister_netdev() was only ever called by the PCMCIA core if
register_netdev() succeeded previously. The lonely exception was
easily fixed.
