Driver core / memory: Simplify __memory_block_change_state() As noted by Tang Chen, the last_online field in struct memory_block introduced by commit 4960e05 (Driver core: Introduce offline/online callbacks for memory blocks) is not really necessary, because online_pages() restores the previous state if passed ONLINE_KEEP as the last argument. Therefore, remove that field along with the code referring to it. References: http://marc.info/?l=linux-kernel&m=136919777305599&w=2 Signed-off-by: Rafael J.
