This patch fixes the usage of uninitialized variables in dmabounce code intoduced by commit a227fb92 ('ARM: dma-mapping: remove offset parameter to prepare for generic dma_ops'): arch/arm/common/dmabounce.c: In function ‘dmabounce_sync_for_device’: arch/arm/common/dmabounce.c:409: warning: ‘off’ may be used uninitialized in this function arch/arm/common/dmabounce.c:407: note: ‘off’ was declared here arch/arm/common/dmabounce.c: In function ‘dmabounce_sync_for_cpu’: arch/arm/common/dmabounce.c:369: warning: ‘off’ may be used uninitialized in this function arch/arm/common/dmabounce.c:367: note: ‘off’ was declared here
