From 33b31152b0e7310d872449f548cd8e3da211f7ea Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 5 Nov 2014 14:01:29 -0600 Subject: [PATCH] ryu: remove board id normalization The gpio_get_tristates() function prints out the values observed while processing the GPIOs. Additionally, the values for the normalization were completely consecutive. Therefore, this indirection can be removed. BUG=chrome-os-partner:33578 BRANCH=None TEST=Built and booted.
