[PATCH libdrm] [drm] - Adding amdgpu_cs_create_syncobj2 to create syncobj as signaled initially

[Christian König]

Reviewed-by: Christian König <christian.koenig at amd.com>

But in general for libdrm changes I would ping Marek, Nicolai, Michel 
and in this special case Dave Airlie because he added the patch with the 
missing flags field.

And I strongly assume you don't have commit rights, don't you?

Regards,
Christian.
