About the subject line -- I'd drop "fix coding style" and wrote about
the specific change you did in the patch (macro rename? Variable
rename?). "CamelCasing" should be simply "CamelCase", I think.
And a small nit -- just one blank line between the commit message and
SoB will suffice.

I just did a quick search, and it seems like "2eSST320", "2eSST233" and
"2eSST160" refer to bus names, so I'd keep them as they are in the code.
For the future, if you're not certain the meaning of a definition in a
driver, you can always look it up. If you're lucky, you might find
documentation for the hardware, or some article about it.
All the best,
Karolina
