From 281ec367bff42304e0dc5cbc8d267ce9251478b7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 11 Jul 2014 10:50:14 +0200 Subject: [PATCH] i2c: efm32: correct namespacing of location property MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Olof Johansson pointed out that usually the company name is picked as namespace prefix to specific properties. So expect "energymicro,location" but fall back to the previously introduced name "efm32,location".
