From cea896238fbfdbce254f51fc8fd78c59df50081f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 20 Apr 2011 09:44:44 +0200 Subject: [PATCH] driver core/platform_device_add_resources: set resource to NULL if !res MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This makes the res = NULL case more consistant to the res != NULL case as now both overwrite pdev->resource.
