This line seems extra.

Also with 'git show --color-moved' I still see some lines are different. 
I guess you fixed indentation and checkpatch warnings in those lines.

Perhaps you can first add a patch to fix those indexation issues in VRR 
related registers in i915.reg and then simple move those regs in the new 
file.
