drm: reorder struct drm_ioctl_desc to save space on 64 bit builds
shrinks drm_ioctl_desc from 24 bytes to 16 bytes by reordering members to remove padding. updates DRM_IOCTL_DEF macro to initialise structure members by name to handle the structure reorder. The applied patch reduces data used in drm.ko from 10440 to 9032 Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>
