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()
