Subject: [ 08/62] ARM: at91: fix at91sam9261ek Ethernet dm9000 irq

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@...osoft.com>

commit ee9dd7631af6fb5c02964ed5b496217cd4ced059 upstream.

You need to setup the dm9000 irq via gpio_to_irq() since
d0fbda9add (ARM: at91/gpio: drop PIN_BASE).
