Checkpatch warns that:

WARNING: The commit message has 'stable@', perhaps it also needs a 'Fixes:' tag?

(I'm the person who created this checkpatch warning.) Fixes tags aren't just
for regressions they're for any bug fixes. So the Fixes tag here should point
to when the driver was introduced.

Even if the Fixes tag points to the first git commit, it's useful information
so, please, always include it.
