From d0643aa16688131b4dfbd03797ad73bab4ff29bf Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 22 Dec 2011 15:07:00 -0500 Subject: [PATCH] pata_of_platform: remove direct dependency on OF_IRQ CONFIG_OF_IRQ is not available on some platforms and using of_irq_* breaks the build. Since resources are already populated in the platform device, get the irq from there instead. Reported-by: David S.
