Those should really be split into separate patches, but as for your PATCH 1/3 it's not worth fixing up the comments this way as they need reformatting anyway.

Those parts of the patch are okay.

That part of the patch has also been tackled in a separate patch by jitendra kumar khasdev. Your patch predates it, but jitendra's patch is split better.
