From 0f2886057be322ddfa4858384c40a505f7a32a4a Mon Sep 17 00:00:00 2001 From: Tom Gundersen Date: Wed, 21 Sep 2016 16:59:19 +0200 Subject: drm: Don't swallow error codes in drm_dev_alloc() There are many reasons other than ENOMEM that drm_dev_init() can fail. Return ERR_PTR rather than NULL to be able to distinguish these in the caller.
