Could you submit in the way with one patch per mail?
At best, use git-send-email with a cover letter.

And, basically for this kind of extension, the only thing to be really
cared is about the compatibility with old kernels.  That is, the
program must run fine with an old kernel without your change in hdsp
driver as well as other rme/hdsp devices to work as it was.


thanks,
