UML: Fix some apparent bitrot - migration of net_device methods into net_device_ops - dma_sync_single() changes Signed-off-by: Paul Menage <menage@google.com> Acked-by: Amerigo Wang <xiyou.wangcong@gmail.com> -- This version is split from my earlier patch, including just the portions that ar required for Linus' tree. Fixes the following compile errors: include/linux/dma-mapping.h:113: error: redefinition of 'dma_sync_single' arch/um/include/asm/dma-mapping.h:84: error: previous definition of 'dma_sync_single' was here include/linux/dma-mapping.h: In function 'dma_sync_single': include/linux/dma-mapping.h:117: error: implicit declaration of function 'dma_sync_single_for_cpu' include/linux/dma-mapping.h: At top level: include/linux/dma-mapping.h:120: error: redefinition of 'dma_sync_sg' arch/um/include/asm/dma-mapping.h:91: error: previous definition of 'dma_sync_sg' was here include/linux/dma-mapping.h: In function 'dma_sync_sg': include/linux/dma-mapping.h:124: error: implicit declaration of function 'dma_sync_sg_for_cpu' arch/um/drivers/slirp_kern.c: In function 'slirp_init': arch/um/drivers/slirp_kern.c:35: error: 'struct net_device' has no member named 'init' Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
