Hi Ville,
You had provided your RB on earlier revision
https://patchwork.freedesktop.org/patch/351873/?series=72468&rev=2
later u have provided the above review comment, as current
patch fixes the above review comment.
can i use your RB for this patch, if current patch is ok.
Thanks,
Anshuman Gupta.
