You should, instead, add the stuff you need to the existing drivers and not
remove them.

> Obsoleted & superseded, please read cover letter for details.

Cover letter is not stored at the git history. So, it should be used
with care, to just help reviewers to see the hole picture, but not
to describe the patches themselves.

So, if there are important information out there, required to understand
why/what/how a patch is needed, this should be moved into the patch
descriptions and not being kept only at the cover letter.

Regards,
Mauro
