From 342d00ae2b85af003f11036484a33e12e906fe92 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 3 Feb 2012 14:50:07 +0100 Subject: [PATCH] ARM: 7317/1: irq: avoid NULL check in for_each_irq_desc loop ARM unconditionally selects CONFIG_GENERIC_HARDIRQS, so the definition of for_each_irq_desc will check that the desc is non-NULL anyway. This patch removes a redundant check from the IRQ migration code.
