Hello,

Here are the two patches fixing minor problems introduced by my
"dma-buf locking convention" series. Thanks to Dan Carpenter who
checked linux-next with Smatch and reported the found issues.

Changelog:

v2: - Added ack from Christian König to the dma-buf patch and improved
      the dma-buf/attachment pointer check.

    - Dropped v1 patch that added GEM NULL-checking to
      drm_gem_vunmap_unlocked() and replaced it with the NULL-checking
      in drm_client_buffer_delete(), like was suggested by Christian König.

Dmitry Osipenko (2):
  dma-buf: Make locking consistent in dma_buf_detach()
  drm/client: Prevent NULL dereference in drm_client_buffer_delete()
