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. v2: Uncoditionally align the size in radeon_bo_create. At least the r600/evergreen blit code didn't to this, angering the paranoid gem code. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
