We looked at how generally files were named in kernel source.

For what it's worth in my 3.16 branch:

$ find drivers/ -type f | grep '-' | wc -l
4308
$ find drivers/ -type f | grep '_' | wc -l
6507

...it seems that there are far more files named with underscores.  If Greg
or Arnd wants the files renamed, fine, but other than that I see no reason
to change this.
