In dma_fence_allocate_private_stub() set the signaling bit of the newly

Good catch, Reviewed-by: Christian König <christian.koenig@xxxxxxx>

Should I push it upstream as well or do you have commit access?

This is clearly a bug fix so better push this to drm-misc-fixes and maybe even add a CC:stable tag.

Christian.
