From: Greg KH
Date: Tue Apr 24 2012 - 19:00:44 EST


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

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

From: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@xxxxxxxxxxxx>

commit ee9dd7631af6fb5c02964ed5b496217cd4ced059 upstream.

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