Sorry, but please understand the issue from our side, because the more
code that's in the kernel tree, the more work that gives maintainers
who stick around for the long term. Therefore, it is desirable not to
collect lots of driver code that is only subtly different from each
other, but require re-use and/or adaption of what is already present.
