Today's linux-next merge of the char-misc tree got a conflict in:

drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c

between commit:

5740211ea442 ("drm/i915/dmabuf: fix broken build")

from the drm-intel tree and commit:

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

from the char-misc tree.

I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts.

This is now a conflict between the drm-intel tree and Linux' tree.

This is now a conflict between the drm tree and Linus' tree.
