Hi all,

After merging the char-misc tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

ERROR: modpost: module drm_shmem_helper uses symbol dma_buf_vunmap from namespace DMA_BUF, but does not import it.
ERROR: modpost: module drm_shmem_helper uses symbol dma_buf_mmap from namespace DMA_BUF, but does not import it.
ERROR: modpost: module drm_shmem_helper uses symbol dma_buf_vmap from namespace DMA_BUF, but does not import it.

Caused by commit

  16b0314aa746 ("dma-buf: move dma-buf symbols into the DMA_BUF module namespace")

I have applied the following patch for today.

 module namespace"
