FWIW, I found that developing the driver outside of the main kernel tree
for merge is the best way to keep a history that's not too interesting
in the kernel tree.

Something like:
https://github.com/hadess/gt9xx
will allow small reversible commits, make it easy to branch for testing
(say a bug crops up, create a branch, fix the bug, get somebody to test
it, merge to master, and copy/paste the files to the upstream git tree
for inclusion).

Of course, in your case you might need to create a backport for the
whole bluetooth sub-system, as it uses internal API, which makes it
harder. But it's still viable for large cleanups, and pre-merge changes
while keeping history.
