From 27a33f9e8fb203e71925257cf039fe6ec623c5d1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 20 Apr 2011 09:44:42 +0200 Subject: [PATCH] driver core/platform_device_add_data: set platform_data to NULL if !data MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This makes the data = NULL case more consistent to the data != NULL case. The functional change is that now platform_device_add_data(somepdev, NULL, somesize) sets pdev->dev.platform_data to NULL instead of not touching it.
