From c2f17e60cbe11b5ff96604ed8d133a0ea83cf296 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 20 Sep 2021 16:10:49 +0200 Subject: [PATCH] drm/gma500: Embed struct drm_device in struct drm_psb_private Embed struct drm_device in struct drm_psb_private. Replace the use of dev_private by an upcast operation. Switch to managed release of struct drm_psb_private.
