Stephen Rothwell reported the following build warning: lib/dma-debug.c: In function 'dma_debug_device_change': lib/dma-debug.c:680: warning: 'return' with no value, in function returning non-void Introduced by commit f797d9881b62c2ddb1d2e7bd80d87141949c84aa ("dma-debug: Do not add notifier when dma debugging is disabled").
