From e112e593b215c394c0303dbf0534db0928e87967 Mon Sep 17 00:00:00 2001 From: Nicolas Iooss Date: Fri, 11 Dec 2015 11:20:28 +0100 Subject: [PATCH] drm: use dev_name as default unique name in drm_dev_alloc() The following code pattern exists in some DRM drivers: ddev = drm_dev_alloc(&driver, parent_dev); drm_dev_set_unique(ddev, dev_name(parent_dev)); (Sometimes dev_name(ddev->dev) is used, which is the same.) As suggested in http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html, the unique name of a new DRM device can be set as dev_name(parent_dev) when parent_dev is not NULL (vgem is a special case).
