The style that you referenced is the most common style, however I saw
quite a few places in the kernel use the style used by this patch so I
thought that it may be acceptable.

$ grep -r SPDX arch/ drivers/ include/ | grep \* | grep -v ":\/"

I'll resubmit the patch next week with hopefully the last bit of
cleanups to get this driver out of staging.
