Re: drm/syncobj: flatten dma_fence_chains on transfer

[Christian König]

Hi Jesse,

not sure how you created this, but usually we use "git send-email" to 
send out patches. That one here looks kind of mangled.

Additional to that this is most likely not the right place for the call.

Regards,
Christian.
