From d940f3065c120af233d36933e94ebb577a695b44 Mon Sep 17 00:00:00 2001 From: Clinton Sprain Date: Wed, 11 May 2016 11:05:35 -0700 Subject: platform/chrome: cros_ec_lightbar - use name instead of ID to hide lightbar attributes Lightbar attributes are hidden if the ID of the device is not 0 (the assumption being that 0 = cros_ec = might have a lightbar, 1 = cros_pd = hide); however, sometimes these devices get IDs 1 and 2 (or something else) instead of IDs 0 and 1. This prevents the lightbar attributes from appearing when they should. Proposed change is to instead check whether the name assigned to the device is CROS_EC_DEV_NAME (true for cros_ec, false for cros_pd).
