dm9000: acquire irq flags from device tree
The DM9000 supports both active high interrupts and active low interrupts. This is configured via the attached EEPROM. In the device-tree case, make sure that the DM9000 driver passes the correct flags to request_irq. Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
