From 3f8435516b1c27c7fdf75ace1de1391d119c65c4 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Thu, 12 Jan 2012 06:10:22 +0000 Subject: [PATCH] kirkwood_spi: correct access to irq_mask register Problem appears to have been present since day one but masked because alignment aborts were not enabled. ca4b55800ed7 "arm, arm926ejs: always do cpu critical inits" turned on alignment aborts and uncovered this latent problem.
