Subject: [PATCH 1/3] drm/radeon: embed struct drm_gem_object
Date: Sat, 13 Nov 2010 21:57:32 +0100	[thread overview]
Message-ID: <1289681854-15505-2-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1289681854-15505-1-git-send-email-daniel.vetter@ffwll.ch>

Unconditionally initialize the drm gem object - it's not
worth the trouble not to for the few kernel objects.

This patch only changes the place of the drm gem object,
access is still done via pointers.
