From d1c627b59c8e69d40b94a4ff28a582a84c6a95a3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de> Date: Thu, 1 Oct 2009 15:44:32 -0700 Subject: [PATCH] spi-imx: initialize complete config struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Otherwise the config function uses random data from the stack. This didn't stick out because config is called once more in the chipselect function with correct parameters.
