 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:
+   - 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.
 * no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
   Instead of the cs_error() callback or the CS_CHECK() macro, please use
