This introduces a new checkpatch WARNING -
WARNING: line length of 101 exceeds 100 columns
#158: FILE: drivers/staging/octeon/octeon-stubs.h:1395:
What happens if you leave the alignment as is, and only make the 'enum'
related changes?
You can send another patch in the future to address the alignment
CHECK's. That follows the one type of change per patch guideline.
