samples: mbochs: add DMA_SHARED_BUFFER dependency
The new bochs vbe sample fails to link when DMA_SHARED_BUFFER is disabled: ERROR: "dma_buf_export" [samples/vfio-mdev/mbochs.ko] undefined! ERROR: "dma_buf_fd" [samples/vfio-mdev/mbochs.ko] undefined! This uses a 'select' statement to enable that framework, like all other users do. Fixes: a5e6e6505f38 ("sample: vfio bochs vbe display (host device for bochs-drm)") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
