	The integer returned by the unload hook is ignored by the drm core, so
let's make it void.
This patch was created using the following Coccinelle semantic script
(except for the declaration and comment in drm_drv.h):
Compile-tested only.

 * alloc_size. If so we allocate new object there.
 | 
						|
 *
 | 
						|
 * When there is not enough room at the end, we start waiting for

						|
 * each sub object until we reach object_offset+object_size >=
 | 
						|
 * alloc_size, this object then become the sub object we return.

 |

 * Alignment can't be bigger than page size.
 | 
						|
 *
 | 
						|
