From b15f052cb8c1ba2a55998707f29dc8a8e5cc40ca Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 24 Mar 2011 21:27:35 +0000 Subject: arm/gpio: Remove three copies of broken and racy debug code gpiolib plus two gpio implementations in arm fiddle in the guts of irq_desc in a racy and buggy way. Remove the stuff. I already told the gpio folks that we can provide that information in a proper way if necessary.
