From e3721749000e11ba3f315efc5c98bf4cd5662f99 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sat, 7 Mar 2015 22:07:07 +0100 Subject: [PATCH] at86rf230: init xtal_trim with zero This patch initialize xtal_trim value to zero. The xtal_trim property is an optional device tree value. Currently if no xtal_trim property is given the xtal_trim value can be contain random data, because it's a stack variable. This patch init the xtal_trim value to zero which is also the default value after reset for at86rf230 transceivers.
