I wanted to start versioning driver after this set patch will be approved.
Also I have plan to add change-log after approval this patch set.
I now treat this patch set as Initial version of driver.
If my approach is incorrect please correct me ??
Maybe before approval the better versioning will be [PATCH vrc4] ?

Yes I know, but most of them are related to "line over 80 characters"
and " quoted string split across lines" warnings. The first group I could correct
but then I will make readability worse.
To eliminate the second group I will have to enlarge the first group of warnings and
the number of characters in single line will be bigger than 100.
