Thanks for the cleanup Pierre :)

I would prefer this to be a patch per module. It doesnt help to have a
single patch for all the files!

It would be great to have cleanup done per logical group, for example
typos in a patch, aligns in another etc...

Not sure if this is a style issue, kernel seems to have 2990 instances
of this!

this does not seem aligned to me!

this one too

It might read better if we move the log to second line along with
dev_num...

here as well.. (and giving up on rest)
