[PATCH] gpio: gpio-ml-ioh: fix off-by-one for displaying variablei in dev_err

From: Axel Lin
Date: Tue Jun 14 2011 - 07:13:13 EST


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.
