This isn't about you, it is about the community.

Looking again into this patch, the only acceptable change is the copyright update.
The driver is still based on softdog. The other changes are your personal preference
only and don't fix any checkpatch issues (and even those would be arguable for
some maintainers). This means that, long term, we might get another patch from
someone else changing indentations and variable names again ... and again ...
and again. This adds no value.
