From 2a6ad871a10ce915a300d8f227168ad4c34936ec Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Sun, 3 Feb 2013 12:24:48 +0100 Subject: [PATCH] ARM: multiplatform: Sort the max gpio numbers. When building a multiplatform kernel, we could end up with a smaller number of GPIOs than the one required by the platform the kernel was running on. Sort the max GPIO number by descending order so that we always take the highest number required.
