pcmcia: dev_node removal (core)
Remove the dev_node declaration. We now only pass the device name to the deprecated userspace tools. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

This file details changes in 2.6 which affect PCMCIA card driver authors:
+* No dev_node_t (as of 2.6.35)
+ There is no more need to fill out a "dev_node_t" structure.
+
* New IRQ request rules (as of 2.6.35)
Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:
