From 33300571b1111264fd0c5701733f7576323f3e35 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 14 Jun 2011 19:12:57 +0800 Subject: [PATCH] gpio/ml-ioh: fix off-by-one for displaying variable i in dev_err with the "for (; i != 0; i--)" sytax, i-- will be executed after the iteration. thus dev_err shows wrong i value. Switch to "while(--i >= 0)" which is better in readability.
