   Hello,
 
 > Oh, I expected this patch to be an improvement over the previous one...
 > Please double check that the patch is applied correctly (4 files changed).
 
   I re-fetch the patch and apply it. A kernel is building now.
 I think the patch is applied correctly, but some offsets were occurred.
 All changes were cleaned before applying the patch.
