Yes they are, thanks for spotting that.  These patches were on drm-msm
/ msm-next when I made this patch on January 11th, hence these were the
hashes given to me by git bisect: see how those patches have an author
timestamp of January 9th, while the proper hashes that landed upstream
have a hash of January 12th: the branch has been force-pushed after.
