Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.

Why are you introducing whitespace changes?

Are you sure that you are not introducing same bugs as other vivo
patches? Do you understand the issue with this scripting work?

Best regards,
